The act of doing one finger push ups in two different vaginas at once.

Also can vary as a Dirty squish-up. (The act of squish-ups in 2 Butts)

Dude I had your mom and your sister over and we did 3 different sets if Squish-ups! Needless to say it got a little messy after the first set.

We got down and did 1 dirty squish up!
