Shell

Most boring chick ever.
A Shell is often a fan of Jersey Shore, Johnny Depp, R&B, and/or Punk rock. A Shell is also an attention whore and will do whatever she can in order to get attention.
These tactics include the following:
Random lame trollings.
Fake chat lesbianism.
References to her boobs/vagina.
Calling a Shell stupid is an act of futility, in her feeble mind "being stupid is cool", and she will almost always be surrounded by boring guy friends who will kiss her ass profusely in order to "tap dat ass", which never happens because Shells only like the idea of sex because it gets them attention, they'll never follow through with it.

All Shells should be booted in the cunt with a rake.

Tammy: I'm naked on cam...blah blah that show Friends blah blah umm blah Snookie blah blah bliggity Soulja Boi!

John: Sigh...What a Shell.

shell shield

When you get a triple green shell or red shell in Mario Kart and keep it as a shield to avoid other shells. Unfortunately, shell shields are busted by the 'naners.

Shells are used to smack people around.

I pulled out a shell shield. Wario, Ludwig, and Rosalina all went down. Then I just sped ahead to first.

Shell shocked

When a cold gust of wind hits a man and his penis retreats back into its body, such as a turtle when it gets scared.

“So did you go all the way with Sally?”
“Nah I got shell shocked before I walked in”.
