McSteak 

Back in the day when you used to add Mc infront of alot of words - this word managed to last the test of time, McSteak is another word for mistake.

It's also funny because whenever McDonalds brought out a steak burger it was always terrible.

Beckett: Max did you try and pick up that Montenegrin girl last night?

Max: Oooooooh what a McSteak that was, complete waste of time as per usual.

McSteamy 

Nickname for Grey's Anatomy character Mark Sloan. Dr. Sloan is played by none other than Eric Dane.

*SPOILER ALERT*
His character first broke up a marriage between Derek and Addison with a one-night-stand with Addison, which turned out to actually be a month long affair. He still has a thing for Addison, and Derek barely speaks to him. Oh yeah, and he hooked up with Callie!
-----
And yet...a well-deserved nickname, did anybody else see that shower scene, the infamous towel?!

"McSexy," "nooo," "McYummy," "noope," definatley "McSteamy!"

misteak 

A poorly prepared steak, cooked at the incorrect temperature or badly seasoned

A steak cooked well-done in actuality is a big misteak, while a steak cooked medium rare is rarely a misteak.

However, dropping a steak on the ground prior to (or after) placing it on the grill is also a misteak.

A - "But it's o.k. That I cheated on Mcdreamy with McSteamy because I'm working my way up the McEamy ladder"

McSteamer 

The act of shitting on a thin, used McDonald's napkin that is lying on the other persons face.

When Kristina saw the crinkled up napkin hanging out of the trash can, it reminded her of the hot McSteamer Thomas gave her last weekend.
