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.

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.
