"I was tryna talk to dis nigga, but couldn't understand his azz, he wuz speakin' Fuckanese. I don't understand that shit nigga, I'm from Realniggalia."
When a guy cheats on his wife so that he can have anal sex with his girlfriend, he is a Fuckanus.
"Jesse is cheating on his smokin hot wife with HER? Nasty! Why?" says Jesses' friend.
"Because his wife won't let him poke her in her bunghole." answers Jesses' other friend,
"But SHE will!!!" hahahaha
"Wow! He is such a total Fuckanus!" replies Jesses' friend.
