The greatest of all arm workouts. Typically done on Friday and/or Saturday, the guido pump consists of fifteen to twenty sets of bicep tricep supersets. One should drink pre workout prior to a guido pump and throw on their smallest shirt immediately afterwards.
I did the guido pump last night, and was feeling juicy as fuck afterwards. My arms were hugging the sleeves so fucking tight.

a foward thrusting motion of the arm in celebration for some gangsta ass shit. while arm thrusting is happening the word "guido pump" must be repeated over and over.

A way to express any awesomeness that a Guido might find awesome. Taking one's arm and thrusing it into the air with a closed fist many times in a row shouting GUIDO PUMP!!! This action originated on the Frog Bus of West Milford High School in West Milford, New Jersey.
