Buttings 

When a girl is too large for her leggins and the fabric stretches to such a degree that you can see her butt crack. Important to note that the girl is not wearing a shirt or skirt to cover said leggings.

That girl has got to lose those buttings. I can totally see her crack.

Balloon Butting 

Balloon Butting is when you stick a balloon into your anus and then have a friend inflate it to induce sexual pleasure, or you self inflate using a series of tubes/straws.

Ya! It totally burst inside of him and he pooped out plastic!

Buttinsk

A word Shawna (or Nanalew on YouTube) and Tessa (or Meekakitty on YouTube) use to describe each other. It can also be used as a synonym for butt or bottom, or an insult.

"She's a big buttinsk."

Nut Butting

When a man and another man ride a motorcycle together. Named that because the one mans nuts touch the other mans butt.

Aaron: Maaaannn, I don't want to go Nut Butting with you.

Head-butting 

When you have sex with a pregnant female. The term comes from the fictitious contact between the head of the erect penis and that of the infant.

"How was your night with prego Sally last night?"

"Let's just say we did some serious head-butting!"

"Niceeeeee"

Butting Heads
