Cart Head 

When you are on a golf cart and receiving a hearty blowjob.

I was riding around with this girl and I got crazy cart head

Carthead 

Similar to a Crackhead but instead it’s the addiction to marijuana distillate vape cartridges

“Hey look it’s the local Carthead, he doesn’t do crazy shit tho, he just likes to chill.”
