The excuse you give to go fuck.
While visiting my parents, Jeff and I usually use the sexcuse of needing a gallon of milk from the grocery store. That gets us out of the house long enough for a quicky in the backseat of the car.

The excuse one may give for having sex with someone that he or she may not normally do so with. Can be given on holidays, birthdays, times of low self-esteem or frunkedness, or when there is a general L.O.S.

Not to be confused with Holiday Sex, where sex is expected but has to be worked for. However, ex sex and drought busters includes times when a sexcuse would be given.
Dude 1: Hey man, what're you up to?
Dude 2: I think I'm gonna go bang out my ex.

Dude 1: Dude, you said you would never touch that ass again.
Dude 2: I need a Drought Buster bad man.

Dude 1: Terrible sexcuse dude.
