Peep 1: Hey where is your roommate?
Peep 2: A girl called so he went to her house to do the nasty.
Peep1: Damn, that boy is addicted to booty calls.
Peep 2: Yeah, he is definitely a bootycallaholic.
When someone of the opposite sex calls you up to "hang out over your/their place" (which in code means come over and have casual sex. Otherwise known as "shoplifting the pootie" -Jerry Mcguire.). It usually happens infrequently, without warning and normally occurs in the late night hours, resulting in hours of intense (if you're lucky lol) sex.
Used to describe what time your casual fuck friend calls you. Usually, takes place anytime in the late late evening. Typically, the call is only to get booty.
