A troll in internet speak is an individual who has no interest in helping out but who deliberately aims to generate anger and discord.
It is assumed that the troll gets two "kicks" from this activity.
- It is amused by the dissent it causes.
- It believes itself the centre of attention and this makes it feel important.
Seasoned internet users will spot a troll's antics and respond by simply saying "Don't feed the Troll".
