To say a very lame joke. Can have different forms such as an adjective and a noun as seen in the examples.

Typically, when someone says a very lame joke, the people around accuse the person saying the joke by doing a hand gesture, consisting of a closed hand with the ring finger, middle finger and index finger open and placed over your forehead.

There is a myth claiming that when a person does a Keith (very lame) joke, he or she are killing a Kenyan child.

When the joke is epically lame, or the person doing the lame joke tries to justify themselves but instead make it lamer, they do an epic Keith. The hand gesture is done over the mouth instead of the forehead, and 50 Kenyan children are killed instead of 1.

Nevertheless, this concept brightens the world and human lives. No one typically laughs at a lame joke, but when people do the Keith hand gesture, then the people laugh at the person doing the lame joke.
(Adjective): That was totally a Keith joke.

(Noun): He just did an epic Keith! Hahaha

A large burly man with patchy hair and a scruffy beard. In the winter can be found wearing a Kelly green Eagles Jersey or a Notre Dame hoodie. In the summer months he can be seen wearing xtra long basketball shorts and an off white colored wife beater and drinking a Bud Light.
Bro, I went to the Eagles game and got attacked by a group of Keiths.

If you don’t need Keef to know that something is Kife, then you’re in Keith. Keith is the reason the lead singer of Shinedown has a brown landing strip on his chin. If you are sober right now and know that that is highly unlikely, your in Keith. If you are sober and believed the previous statement to be true…then your the lead singer of Shinedown and should probably brush your teeth once Keith is done.
Ew…My breath tastes like Keith!”

Everyone has a Keith. A Keith is that guy who cheats on his girlfriend and has hella girls on the side. Keith continuously encourages your own boyfriend to be just like him. Don't be a Keith.
