getting one's freak on 

(verb construct) Indulging enthusiastically in one's favorite acts of sexual congress, esp. those activities most likely to appall mainstream society which one secretly enjoys best of all; wanton sexual gratification.

Standard usage limits definition to interactions with at least one other partner — but in hardship cases, this requirement may be waived to encompass solo practitioners so fugly they only get they freak on by theyselves.

I ain't sleep for shit last night, damn loud-ass skanky roommate up in there gettin' (her) freak on.

Long as you don't mind me getting (my) freak on before I bring her home, I be happy to take yo sister to the dance.

One often loses all track of time while getting one's freak on.
