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.

He left his house; he should have stayed
He went to work so he'd get paid
So he'd afford his brand new maid
Other things that make life great
He hopped a bus and then a train
Few more stops he'd have it made
But something happened on this day
That put this man into his grave
The train broke down he took a cab
He told the man to make it fast
They ran into a concrete slab
Then cries and screams for many times
He left the cab, walked down the street
There a person he did meet
Who thought his gun was pretty neat
And wanted to see someone bleed
Stumbling on for two more blocks
His body was in total shock
Punch in time was eight o'clock
He's hours late, so he'd be docked
Twenty feet from where he worked
He fell upon some teenage jerks
They took his cash then went berzerk
And killed the poor old office clerk
He should have stayed home
He should have stayed home
He should have stayed home
