The backwards whale is a sex move. In this move the
guy is sitting on the chair and the girl is standing directly over his penis. The
guy then uses one hand to support himself holding onto the chair and he slowy moves up kind of looking
like he is going to do a bridge move from gymnastics making a whale noise, (similar to the one dory makes on finding nemo.) and then thrusts upward violently saying
BAM! Very loud. Thus completing the backwards whale.
Guy1: Bro I pulled the backwards whale on my girl last
night.
Guy2: Oh yeah? Did you make the whale sound?
Guy1: Yeah I sounded like this, "whaaaaaaaaaaaaaaaa
BAM!!!!"
Guy2: Hell yeah that sounded just
like Dory from Finding Nemo! Kudos!
