shellmac 

A recently popular troll in the GD, occasionally flirting with hot guys, but mostly calling everyone else names.
It has incredibly low self-esteem, despite what it says, and will get even more hostile if you question it's self-worth.
The shellmac often gets itself banned, and makes duplicate versions (Shellmac v17, v18, etc)
The best course of action when being trolled by shellmac is to ignore it, like any other troll. If the shellmac flirts with you, insult it. Eventually it's self-esteem will get so low, it will give up and kill itself.

Gaian: "Agh, I hate Shellmac so much, she called me fat!"
Shellmac: "You are fat. And you don't hate me, you're just jealous of me because I'm more popular than you."

Poster1: "Bitch. You're just jealous of me."
Poster2: "Don't be such a shellmac."

shellbacker 

straight military guy, usually Navy, who does gay "solo jerk-off" videos for gay guys for extra cash...a profitable endeavor that doesn't make them gay...just means they are confident with their packages and love getting paid money for something they usually do for free by themselves...

golden shellback

adj. A US Navy (and possibly other nations) tradition that occurs when a ship and it's company crosses the equator and the international dateline simultaneously. In doing so, the wog, and even plain shellbacks must go through an initiation process; an accepted form of hazing in todays military. Its should also be noted that when the dateline is crossed, you skip a day. Davey Jones Himself as well as Neptune join in on the fun as well. After all is said and done, a steel beach picnic usually follows this time honored tradition.
