laffin
Laffin kid is when you see something funny but you’re too lazy to react, so you just say ‘laffin’ and walk away like you’re the king of the world.
This joke is fire, but I’m too lazy to laugh, so I just said ‘laffin’ and left.
Saw the funniest meme ever, but I just typed ‘laffin’ and walked off.
He made a joke, I said ‘laffin’ and that was it.
