Radio Kill 

To completely annihilate any interest in a particular song by overplaying it on the radio.
Any song that is played around 50 times a day is effectively radio-killed

In order to effectively radio kill songs like "You're Beautiful" (which is akin to beating a dead horse since the song blows anyway), one must play it repeatedly on all the shitty radio stations until the playcount reaches 6 figures and people go postal from even hearing part of the lyrics.

98% of Christmas music is radio-killed at least a month before the actual Christmas day.

Radio Killer 

Term for a rapper who spits hard but won't get play on the radio due to extenuating circumstances (i.e. censorship), thus detracting a large audience from listening to the radio because they're banging his shit on their own systems instead.

Wyatt: "Yo man, you peep that new Dead Prez joint?"
Donzell: "Naw, you heard it on 93.7?"
Wyatt: "No way! They some straight radio killers, I heard that shit through the wire and popped it straight into my box."
Donzell: "That's what she said."

RADIO KILLA 

A girl so incredibly hot, perfect and gorgeous, every sane guy is completely paralyzed and unable to speak the slow-motion seconds she walks by. Even the music stops.

Four guys are chilling on a bench, laughing and joking when suddenly a radio killa walks by.
Dude 2 (LOUD): YESTERDAY GUYS, I FARTED SO HARD MY GR...
* Radio killa walks by *
Dude 1, 2, 3 and 4: ...........

kill ratio 

in gaming, the number of kills in relation to the number of deaths by a player

an even kill ratio would be 1:1, where a player has killed as many opponents as have killed him

most players strive for a 2:1 kill ratio or higher

Kill Death Ratio 

The Kill Death Ratio, Commonly Referred to as K/D, KDR or Kill/Death, is the average rate of the amounts of deaths you need per kill. For instance, a KDR of 1 means that your number of death equals the number of kills you have. If your KDR is lower than one, then you have more deaths than kills, and vice versa.

Summary (may require some mathematical understanding):
If 0 < k < 1, or log(k) < 0, then you are a n00b.
If k > 1, or log(k) > 0, then you are a good player.
(k is your Kill Death Ratio)

Guy 1:
Duude! I'm l33t!
