John motherfuckin' Smith 

Refers to one of the most unknown badasses of all time. John Smith beheaded 5 Turks, was imprisoned, killed his master, escaped, sailed to the new world, made a shitty colony a great one, jumped off of an exploding ship, suffered burn injuries, and still explored more of the new world. Often refers to the unpopular kid that actually has a shit ton of bad ass acomplishments.

"Hey, Shaun! You know the kid that sits in the corner? Well, it turns out he's a John motherfuckin' Smith! I hear he has seven Soccer MVP medals and a black belt in

Tai Kwan Do!"

horny as a motherfucker 

Simile putting an emphasis on the author's need to have some form of intercourse. A motherfucker is one who has sex with his mother, and the author is in such an aroused state that he could have intercourse with even his own mother.

come on ho, get those clohtes off! I'm horny as a motherfucker out here.
