Top Definition
A naturally occuring phenomenon of an erect penis growing beyond its standard capacity. This rare occurence happens usually after hours of intense sexual intercourse.

This is generally not a problem unless your partner is very petite.
A seven-inch erection becomes eight inches. An eight-inch erection becomes nine inches, and so on.

Sentence: Mr. Smith experienced an over extension of his penis while he pulverized his slam pig last night.
