Derail

The act of making any discussions gone off-topic

The extreme form of derailing is trolling, and because of the trolls, any discussions gone into flame wars/insult wars

Please don't derail the discussion, it's rude

Derail

<Verb> The act of blowing a joke or a rip, usually by sputtering out sentence fragments or by stuttering. This usually leads to laughter by one's friends and extreme embarrassment to the person who 'derailed.' The offender will stay very quiet for a long period of time following one of these outbursts.

"Man, you're so stupid when god handed out brains you thought he said trains...and you went...and got on...and went for a ride...wait....goddammit!!!"

"HAHAHAHAHAHAHAHAHA HOLY SHIT, you're retarded!! Nice derail, Jay!!"

I was getting slammed and was tired so I derailed with no hands and went to bed.
