The act of performing intercourse with a woman while her vag smells like canned tuna that's been sitting out.
"I heard Vincent had a tuna smash yesterday"

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.

Once the couple had twins, they couldn't transport any friends unless they wanted to climb into the smash seat and sit between the babies.

A move commonly used by retards directly after witnessing their non retarded siblings play Super Smash Bros. This move is generally used in combination with retard rage and retard strength. Pretty much it when the tard in question starts smashing shit for no reason other than pure retard enjoyment.
Hey Billy what the hell is your retarded brother doing with the kitchen table over his head? Oh, he's just doing some retard smashing. Retard smashing? Yeah he's all retard raging and picking up heavy shit and smashing it... Don't worry he won't hurt you!
