Panama Pump

The 'Panama Pump' is a sexual act involving two women and two (or more) men.
One women lies on top of the other perpendicularly, with both women on their backs. The girl on the bottom holds the one on top in a 'Bow-and-arrow-submission lock' and multiple men are free to enter her either by the mouth and vagina and/or anus. Additional men are then free to enter the women on the bottom in all orifices.

'"Hey man,were those Slevin girls over here last night?"'
'"Yeah dude, we totally Panama pumped those b*tches!!!"'

Panama City pump

When you're on vacation and you find a gym or something slightly heavy (beach chair, bag, cooler, natty pack) to get a quick pump before you hit the beach. Used to effectively moisten the ladies.

Hey bro I'm gonna go get a quick Panama City pump before we storm the beach like Normandy.
