When you're banging a member of your family from behind and at a random moment you clap their ears. As they're laying on the floor in pain you pull out a life alert necklace, hit the button, and bail.

Bro, my second cousin was over for Thanksgiving...she's so hot I had to try to smash. After a few minutes it felt weird to be banging my cousin so I hit her with the Alabama Flashbang and told my family I had to leave for work.

Philadelphia Flashbang

Philadelphia Flashbang

Imitating the effects of a flashbang, temporary blindness and deafness, the Philadelphia flashbang is the sexual act when a man thunderclaps a woman from behind (clap both ears at once) and as she turns around he jizzes in her eyes. Thus blinding and deafening her.

Sean pulled a quick Philadelphia Flashbang on Oliva and she had no clue it was cumming.
