Simple.
Post statement followed by "Amirite?!"
Person below you will say "Heck Yeah!" or "LOLNO!" in relation to whether or not they agree with your statement. Followed by their own statement. Rinse and repeat.
I think this thread existed but I couldn't find it so maybe it was deleted when the den was changed around a while ago.
This thread will reach ten pages of posts before this time next week, amirite?!
