A Balboa is when you are fucking a girl (probably a loose one) and you want to have her tighten up so you punch her in the gut causing her abs to contract and tighten up her pussy thus resulting in more satisfying sex.
This bitch I picked up from the strip club was so fucking loose I have to use the balboa on her.
