A handjob in which Latin American/Mexican dressings/condiments are used as lube. I.E. salsa, guacamole, sour cream, hot sauce (if you're kinky) etc.
I was with this totally hot puerto rican chick last night.
Dude, did you bang her!?!
Nah, but she did give me a Guatemalan handshake.
when you skin a guatemalan and roll up the skin and eat it.
Hey man you.. you ever tried this guatemalan rollup?
