If you fail to pick a lock, you can punch or kick the object and add a bonus to the pass/fail check. However, this automatically opens the object if the check is successful, and may be noisy enough to alert nearby enemies. In Van Buren, this check was 5 times your Lockpick, out of 1000. In J.E. Sawyer's Fallout Role-Playing Game, this was the results of a 10-sided die times 5, plus your Security skill, out of 100.
Behind the scenes
This is a reference to Fonzie from the sitcom Happy Days, a character who would regularly forcefully hit the Jukebox in his local diner when it wasn't working and it would suddenly be in working order again. "Ayyyyyy!" was his catchphrase.
The perk description was posted by J.E. Sawyer on the Interplay forum in 2003.
