A strange sexual act that refers to a girl who was been menstruating for three days with the same tampon in. The guy positions himself under her and "pulls the plug"--this results in a very messy expulsion of red liquid much like when you remove the pan on an automatic transmission.
Dude! Last night my girl finally let me do a tranny flush, and it was so awesome as it gushed all over my face!
