Mantis 

A gay dude who wears a lot of bird shirts and walks like a praying mantis. This person is also known to grossly over-exaggerate everything.

Jeff: Hey, check out my new bird shirt. I got it at Express because it has a bird on it, and I liked the color.
Kris: Um, nice.
Jeff: Feel this fabric.
Kris: Uh, I can’t dude. I sprained my finger playing Halo.
<Later that night>
Jeff: Hey Logan, did you hear that Kris broke his collar bone in a bar fight last night?
Logan: You are such a mantis.
Jeff: Cassandra’s left nipple is purple. :(

mantis 

Word decribing how a girl behaves towards guys. It can be used as a verb or as a noun.

The female praying mantis bites the head off a male during sex to encourage ejaculation. If a girl is being a mantis, or doing a mantis, she's going quickly from male to male, getting what she wants.

Did you see Jess and Steve? He bought her dinner and a necklace and she dumped him, she did a total mantis.

Krystle fucked three guys this weekend. What a mantis.

Mantis 

This word describes the drunken physical mind set, movement and actions of an extremely damaged individual.

Similar to getting totally T-Rex'd, when one does the mantis they are much more socially awkward yet still very much involved in conversation with friends or while on the pull.

This epic state of drunk foolishness although hilarious does have the drawback of disregarding any thought of invading other people's personal space.

It is not unusual to find the mantis on the floor refusing to call a night 2 days into the sesh!

Everybody do the mantis!
Let's go out and get totally mantis'd tonight!
Dan youre an absolute mantis lad!
