The "swamp-gas" smell you get when you split a chicks pussy open and your dick goes from hard to soft in 0.05 seconds.
The other night I was with this chick. I bent her over my couch...Cracka-lacka...I busted that pussy open. Her pusstank was so strong that my eyes water and my dick tucked between my balls.
When you go into a restroom with flip flops and the person next to you is splattering piss on your feet. Or in rare occasions it can be your own.
My girlfriend asked me why my feet were all wet after leaving the restroom at the state fair. I explained to her that I was just pisstall whipped in there, but it's ok.. my feet were hot.
