In computer programming, overkill is referred to writing excessively more code than needed for a certain task. It can also mean writing up an endless function for which an already built-in one is available, and that the written one can even be less stable.
Foo wrote a 97 line function to calculate days between two dates when all he could have done (using php) is convert the Gregorian Dates to Julian Dates using built-in function GregorianToJD() and execute a simple subtraction, now that's overkill. This would reduce the code to 2-3 lines.

Taking something that was awesome and overusing it so much that it starts to suck, and become annoying. Usually done by the annoying outsider in the group who doesn't know when to stop. Ofter this occurs by going too far with it, as well.
Person A - Hey remember when blah blah blah...
Person B - That was a month ago. It was barely funny then, and it isn't funny now. Overkill!

Person A - Man, the only way you could have gotten that mark was by sleeping with the teacher!
Person B - Shut up.
Person C - Yeah! You must have like. Spread your legs to pass for anything, and screwed every teacher up the ass!
Person A - Yeah, you just overkilled it.

A word popular amongst people who play MUDs or other MMORPGS. To kill with an excessive amount of force usually in unfair Player VS Player fights.
In a Mud I use to play (called MUME) this was the most classic example:
Player1 attempts to fight Player2 in a fair fight. Player2 gets his ass kicked and calls for backup. Player1 gets trapped or Spam killed by Player2, Player3, Player4 and Player 5.

Verb/ A term used in Final Fantasy X which means that you did a massive amount of to an enemy who had a smaller amount of life. In real life it can be used when someone kills a joke or tells a dead-on-arrival joke and tries to add to the joke to make it funny but ends up destroying it even more.
guy1: dude listen to this joke
guy2: k
(guy1 tells a bad joke)
guy2: that sucked
guy1: no, no, no you don't get it let me explain
(guy1 explains and throws in some extra stuff)
guy2: please dude don't overkill
