Keith 

In Left 4 Dead 2, he is the buddy of the survivor, Ellis. He grew up in Savanah with Ellis together, having all sorts of adventures, They were separated when the infection began, but Ellis still brags about his buddy Keith whenever he gets the chance.
Keith has supposedly survived these, as well as several other incidents, as explained by Ellis:
Burned on 90% of his body on multiple occasions.
Thrown through a car windshield breaking both of his legs.
Ran over by his own mower. 90% of his body cut up.
Teargassed.
Bombed with chemical, frag, and incinerary bombs.
Stabbed in the back by a ghost, or possibly a hobo.

There is some speculation whether Keith is a real person or not.

"This one time, me and my buddy Keith..."
"Ellis, not the best time."

A Keith,
A Guy that is so amazingly hott he doesn't know it. He really has no clue. Funny, considering he is so intelligent you think he'd get it.. Has a really handsome smile and these bright eyes that make you shiver and giggle. He's sweet natured and kind. Goofy and tends to do weird things like try to make you fart or bite your nails for you.. but probably the best guy you'll ever meet. Keith's are a catch and you usually don't know what to say to them except nervously texting "your awesome." Don't let him pay for you every time, it's amusing to see him get mad at the chinese lady for taking a girl's credit card over his. P.S. Amazing in Bed. Freaking Amazing. So pleasing it's unbearable.

Me: Keith! You are so sexy
Keith: No, I'm not.
Me: Seriously, Keith, Do I have to post pics to make you believe me?

Keith 

Someone with a very strange sense of humour, usually someone who never gets round to moving out from his mums, tends to attract strange minx like creatures who worship the ground he walks on

minx: do you have your own place?
boy: No, I still live at home.
minx oh, your a Keith

Keith is a kind of guy who is extremely goofy and yet serious about a lot of the time. He is also the guy who does anything for his girlfriend and spoils her a lot but when he is free he tells his buds to hold his beer

Hey have you seen Keith he's kind of a moron but very funny funny.
