Before ejaculation, the male yells "DRUMROLL PLEASE" and proceeds to spread that buttery ass and hit them cheeks in the rhythm of a drumroll. After a satisfactory time the male hits the ass extra hard and ejaculates right in the kisser.
A sexual act where the male ejaculates into his own hand and then vigorously and most unexpectedly slaps his partner in the face with the goo filled paw. Typically used in conjunction with the rusty trombone however can be incorporated into just about any exciting encounter.
She had her tongue buried so far up my ass I exploded into my hand, what was I to do with a fist full of giz? Had to give her the big finish.
OMG dude It was incredible. I came so hard but dropped a huge fart at the same time. A total ripper. It was amazing, but that wookette was like wtf get out of my tent. So I bounced. Big trombone finish, FTW!
