When you're doing a girl a doggy style and just before you blow, you put your arms in the air and jump up and down like Rocky Balboa on the art museum steps. (often followed with the Philadelphia Rocky Ending)
"I was banging Maria doggy-style last night...and I don't know what came over me...I must've been high or something, because I pulled out the Philadelphia Balboa Bounce on her."
"What happened then?"
"She started laughing, so I gave her the Rocky Ending"
