21 N.C. App. 679
STATE of North Carolina
v.
Margie BUTLER.
No. 7419SC405.
Court of Appeals of North Carolina.
June 5, 1974.
*572 Atty. Gen. Robert Morgan by Associate Atty. Gen. Robert P. Gruber and Associate Atty. Norman L. Sloan, Raleigh, for the State.
S. H. McCall, Jr., by Carl W. Atkinson, Troy, for defendant appellant.
CAMPBELL, Judge.
The defendant contends that it was error for the trial court to sustain an objection to her testimony as to threats she had received. G.S. § 14-33.1 provides:
"Evidence of former threats upon plea of self-defense.  In any case of assault, assault and battery, or affray in which the plea of the defendant is self-defense, evidence of former threats against the defendant by the person alleged to have been assaulted by him, if such threats shall have been communicated to the defendant before the altercation, shall be competent as bearing upon the reasonableness of the claim of apprehension by the defendant of bodily harm, and also as bearing upon the amount of force which reasonably appeared necessary to the defendant, under the circumstances, to repel his assailant."
The testimony in question was as follows:
"I had received conversation about the fact or accusations that I had been dating him. I have received threats. On that very day all that happened I had *573 heard, right when I was getting off the school bus, that she was going to shoot me.
MR. ROBERTS: The State objects, your Honor.
THE COURT: Sustained."
The testimony of the defendant was hearsay. There was no showing that the alleged threats came from Mrs. Whitaker. The principle of G.S. § 14-33.1 that prior threats are admissible in assault cases where the defendant claims self-defense does not apply until the evidence of threats is properly presented. State v. Clontz, 6 N.C.App. 587, 170 S.E.2d 624 (1969). We would point out that the trial court did not strike the objected to testimony or instruct the jury to disregard it, and thus defendant had the benefit of it anyway.
The defendant next assigns as error certain portions of the charge. No exceptions appear in the record and the defendant has not specifically identified those portions of the charge which she finds objectionable. This would be grounds for overruling defendant's assignments of error. 1 Strong, N.C. Index 2d, Appeal and Error, Sec. 31 (1967). However, we have decided to consider the merits. Defendant contends that it was error for the trial court to fail to charge on communicated threats as they relate to apparent necessity and what force defendant might lawfully have used to repel the alleged assault by Mrs. Whitaker. However, there was no competent evidence of any communicated threats made by the prosecuting witness and no charge on this point was warranted.
Defendant further contends that the trial court erred in its definition of "reasonable doubt" in that the court did not charge that a reasonable doubt may be based on a lack of evidence. No error was committed in the instant case for the judge did not charge "that a reasonable doubt is a doubt based upon reason and common sense and growing out of the evidence in the case". It is when those words are used that it is error not to go further and add "or the lack of evidence or from its deficiency". State v. Braxton, 230 N.C. 312, 314, 52 S.E.2d 895, 897 (1949). The trial court fully charged on reasonable doubt in this case as follows:
". . . A reasonable doubt is not a vain, imaginary or fanciful doubt, but a sane, rational doubt. The proof beyond a reasonable doubt means that you must be fully satisfied, entirely convinced or satisfied to a moral certainty of the defendant's guilt." State v. Bryant, 231 N.C. 106, 55 S.E.2d 922 (1949).
Finally, the defendant assigns as error the failure of the trial court to define the term "aggressor" when he charged the jury that self-defense was only an excuse if the defendant was not the aggressor or if she voluntarily entered the fight but thereafter attempted to abandon the fight and gave notice to her opponent of her intention to abandon the fight. The trial court's charge on self-defense was correct. The use of the undefined term "aggressor" was not error as it is a word of common usage and in the absence of a request for special instructions such words need not be defined. State v. Jennings, 276 N.C. 157, 171 S.E.2d 447 (1970).
We have considered defendant's other assignments of error and find them without merit. Defendant had a fair trial free from prejudicial error.
No error.
BROCK, C. J., and BRITT, J., concur.
