the inappropriate, overused and cringeworthy use of the colon in internet comments to express unoriginal and unenlightened ideas through the memeification of modern speech. In other words, a dead giveaway that you're a tasteless moron. Generally in the form of an either or question being answered in colon form with the word "yes".
For example,
Me: So are you retarded or do you just lack any kind of originality and thats why you just copy what everyone else is doing on the internet?
Internet commenters: Yes.
Company: We're making this new thing you want
Internet commenters: I'm jizzing myself
Me: Stop coloning and just say you like the thing. Just say "i like this thing". Coloning is completely unnecessary.
Watch out son you'll end up Cooning around with the Coon's-Eye... "That old Farm Man Telling His Son He's A Man Now. Stand Up For Your Self Son. Time To Be A Man ;)
