A hypothetical singular form of the noun secks
. A round of sexual intercourse
is composed of infinitely many secks, much like the area under a curve in integral calculus
is composed of infinitely many line segments. The use of "seck" is hypothetical because it is impossible to give or receive only one seck.
There are no examples of isolated secks because, while their existences are mathematically deducible, they are physically unobservable.
