The technique where a
man or woman becomes attracted to someone and proceeds to have
sex with the person. After the sexual intercourse, the smash and dasher immediately runs out of the premises and never communicates with their partner again.
The technique prevents a staid relationship and it can be done a plethora of times, until an
STD is contracted. A good tactic for when someone, especially a parent walks in on the intercourse. Also used as a great of bragging to
friends.
