Its when a man is getting a blow job and his partner has a pepper in their mouth forcing the pepper and seeds of pepper into the hole and sucking them back out to end the Wet Back Head.
Man, i woke up this morning and my dick was on fire. Must have been that wet back head i got last night.

Another name for a Mexican shower. Running your head under the sink instead of taking a shower.
"I'm late! I guess a wetback head will have to do."
