a hand motion that simulates masturbation.

to perform properly, start with your fist cupped as if ready to masturbate away from you body, bring your hand down to your crotch as if it were a mortar round being dropped in a mortar tube and then open your hand and return very quickly to the starting position. this simulates the mortar round exiting the tube and it looks very much like a wad of jizz being ejaculated from a male one eyed monster.
im gonna go fire my mortar{followed by the hand motion}.

im firing the mortar on the hooker's face {hand motion}

i just fired my mortar all over that hooker's face {do the hand motion}

anytime i get nervous my mortar fires prematurely {hand motion}
