This is typically the moment of realisation that you just sent a dirty text message to a close member of family, typically your mother, rather than the intended recipient.

Recipient: Mum

!!!1!11!!!oneoneeleven 

Used in long uses of exclamation marks, the !1one is an intentional mistake that jokes about the appearance of numeral value "1" in exclamation overdoses. This is due to the shift key not consistantly being pressed while tapping "1" for the overused "!"'s. The intentional error may signify even more exclamation marks, like some kind of lunatic scientific notation.

Chuck : What the Heck!!!1!1!!!.
Steve : Ha Ha Ha !!!1!11!!!oneoneeleven
Chuck : Thats not funny

on one 

Just generally trippin', tweakin', weird, actin' a fool, blackin' out, goin' off. Not necessarily due to drugs, though that's the obvious reference.

Homie was on one, just buggin' like I shot his mom or something.
