Untroll 

When after trolling you realize you fucked up and attempt to fix it by admitting you were wrong or complimenting the person you were trolling.

I felt so bad about trolling Zak that I spent the whole night untrolling him.

Untrollable 

An untrollable, is quite possibly, the rarest of all trolls! They are created, when a cannibal troll, mates with a regular human. The untrollable's, troll side, is dormant for the most part, only coming out, when the untrollable is being trolled. These trolls go about business, like any other internet person. When threatened by a troll, the untrollable will waste the time of the troll, pretending to be too nice. In reality, the untrollable finds amusement, in the troll's feeble trolling attempts. The regular troll, usually realizes that it's being counter-trolled, and stops. When the untrollable finds that the troll is not there, the untrollable usually feels empty, but returns to his everyday life. The only way to troll an untrollable, is to troll them, then stop suddenly.

Troll: Yiff in hell, furfag!!!
Untrollable: Only if you're there. Johnny's not as big as you are.
Troll: Fuck you.
Untrollable: Murr!
Troll: Fag!
Untrollable: Only for you, m'love!
Troll: Britfag piece of shit.
Untrollable: Yes, my dad was a British anus.
Troll: **realises he's being counter trolled** Fuck this shit.
Untrollable: Okay! *takes fecal matter* UNF!!! UNF!! UNF!!
**no response**
Untrollable: **feels sad**

Un-Troll 

The act of trolling resulting in the gratitude (or non-anger) of the reader.

Person 1: Dude. You're such a troll.
Person 2: Nah, man. I'm an un-troll.
Person 1: So you're a fail troll.
Person 2: I bring smiles, not hate. I un-troll.

unroll the stone 

To get out of bed, especially after a long period of sleeping.

I was up much of last night partying, so it was nearly 2pm before I decided to unroll the stone today.
