Gooch Throb is a condition that results from extreme excitement whereby the male's gooch becomes swollen and red, and a slight throbbing can be felt internally in the region of the gooch.

Gooch throb is not sexual excitement which would result in an erection (see boner or hard on) it is only possible to have Gooch throb in a non-sexual situation.
Z Dawg: Hey dude I am sooooo excited about game-a-palooza II tomorrow that my freakin' Gooch is throbbing

Captain Spanky: Whoa Dude, you need to calm down, it sounds like you've got a bad case of Gooch Throb!
