with no discussion in the body of the message, i.e. where you are reading this now, put some variation of yuku? I understand nm (no message), but yuku, kicku, obamaku?
yuku forces you to put something in the body of the post. So instead of NM, they put some word with -ku on the end because yuku is forcing them to do it.
And I swear I am not trying to give you ****... But what the hell does that have to do with this thread? For the record, some of the "ku's" are hilarious and I hope they continue. Jim Halpert has damn near perfected them, y'all could take notice. Who cares where it started. Some suck, but some are funny as ****. I vote to for keepin' 'em.
