slushin 

the act of using a slushie machine without paying. When a store puts out slushie machines outside of their store and instead of purchasing a 3 dollar slushie, you ask for a water cup, dump the water out, and fill the cup up with whatever flavor slushie you like.

Dude, want to go slushin later.
