l4t0r
A way to say you're leaving, but you're also saying you're better than the person you're leaving. It's like bragging while you're leaving.
L4t0r, I'm going. You're staying. I'm the cool one.
L4t0r, I'm outta here. You're still here. I'm the smart one.
L4t0r, I'm leaving. You're staying. I'm the better one.
