LOEWIYD stands for Lots Of Evil Warriors In Your Direction, and is used often in texting to say I hate you, or I'm going to kill you, and wants to use something more serious than a grumpy smiley.
Texting:
Matt: Um, Christy?
Christy: Ya?
Matt: I'm sorry, but I don't really want to go out anymore.
Christy: So you're dumping me!? LOEWIYD!!!
Get the LOEWIYD mug.
