It’s the same stuff the at turns frogs gay.
Every time Earnie sniffed really hard he was sniffing Hetfet placed under his nose, luckily he plays old school RuneScape and won’t turn out homosexual or even worse hobosexual & addicted to crack.
Whenever someone sniffs in really hard they're snorting this term representing Feterosexual and Hetamine.
"Thank God I didn't drink the last little bit of water in my glass because that's hetfet Jimmy", Cartman said to Kyle. "Did you just call me Jimmy"? "Yes, It must be the hetfet. I'm not kidding, but im kidding, or am I"? Cartman said to Jimmy, while nudging him.
