The Killers are a "pop/rock" band from Vegas.

-Their singer Brandon is a sequin wearing mormon.
-Their bassist Mark looks like Jesus
-Their drummer Ronnie often looks like he is "sexing" his
drum set.
-Their guitarist Dave has a nice a**

People not only go to their concerts for music, but also for their daily a** fill.

There you go, The Killers have nice a**ess
that is, according to their "victims"
because "victims" scare the s*** out of me!
"Oh did you see Dave shake it like shakira last night at The Killers concert?"

Someone who kills the plans of evening, or the night when everyone is suppose to hang out. They "kill" the evening. People who repeat this process over and over are labeled "the Killer". Also by ditching your long time friends to hang out with other people is also a act of killing
Matt does not want to hang out or do anything anymore, there for he is a killer.

Matt hangs out with a ugly girl, instead of with his friends, and kills the evening

A horribly overrated band that a whole bunch of trendy TRL fucks like because their songs have catchy beats. However, my three-year-old cousin could pen better lyrics than those assclowns.
Somebody told me
That you had a boyfriend
Who looked like a girlfriend
That I had in February of last year

What the fuck is that shit?
