foul tip 

When you take a particularly large #2 and , upon release, it falls forward and hits the tip of your penis inside of the bowl.

I just had to hit the head post-Chipotle, and it was so big that I had a darn foul tip.

Foul Tipped 

The act of having sex with a girl that has a foul odor between her legs, and only able to get the tip of a males penis in her before gagging.

I was going to bang that chick from the club last night but I only foul tipped her, she stunk so bad.
