schnail!

When someone goes to pound their fist against yours, you move to the side and make a peace sign, and if you look at both hands together, you've made a SCHNAIL! You must yell "SCHNAIL!" when this occurs.

Yours is the head of the snail and the other person is the shell. Therefore: snail + shell = SCHNAIL!

He went to give some love, but instead he got schnailed. SCHNAIL!
