Dirty Toadstool 

the act of inserting your big toe into ones anus

When Alex wasn't looking i sneaked him a Dirty Toadstool.

When i woke up with Alex's toe in my ass i realized that i have just been Dirty Toadstooled.

Dirty Toadstool 

the procees of jamming as much of your foot as possible into someone's asshole

When Alex sat on my foot, my dirty toadstool almost popped his prostate
