The graphable curve by which men can measure the frequency with which they receive blowjobs over the lifetime of a relationship.

If x=days spent in relationship and y=number of blowjobs-per-month, then as x increases, y decreases. The curve usually looks like the positive side of a hyperbolic graph, starting with y being very high and eventually reaching somewhere between 0 and 1, actually hitting zero if the relationship is in the marriage phase.
Dude 1: I used to get a lot of blowjobs, but they tapered off and eventually stopped happening. The standard cycle.

Dude 2: My standard cycle is a straight line that never goes above one.

Dude 1: Your wife sucks.

Dude 2: No, she doesn't, and that's the problem.
