I downed a half pint of scotch and spent the rest of the night derailing old girlfriends.

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

When you fuck someone really hard.
You fuck someone so hard it's like a train getting derailed off the tracks.
"Greg derailed that bitch"
"I thought he had mono!"

Derail; a verb. Used to indicate the exact point of derailment, AKA EPDI (Exact Point of Derailment Indication) A topic is derailed when someone clearly goes off-topic with posts which are obviously not associated with the original topic subject, or goes about anally raping the topic tavles by posting huge-ass pictures.
Let's derail that fucking topic!

That topic is bound to derail.
