Guacplay

Guacplay is when you use guacamole in a sexual way. This could be jerking off with guacamole, using it as lube, rubbing it onto someone's body, etc.

"Did you hear about that new method they came out with?"
"No what is it?"
"You basically rub a layer of guac into her back and draw penises into the guacamole with your finger."
"Oh dude that sounds sick... Guacplay has really taken off these past few years."
