Me: Hey Joe, updog.
Joe: What?
Me: Updog.
Joe: What's updog?
*Facepalms*
Me: Lol in the corner.
Listen up, nimrod! You're probably the type who still asks what 'smh' means. This is a classic bait-and-switch. The first person says "updog" to trick the other person into asking "What's updog?" so they can respond with "Not much, what's up with you?" It relies on the other person not knowing it's a setup. Get it now, Einstein?
