look up anything, like your first name:
1. seized
to get absolutely shitfaced drunk and stoned
"Me and steve were just fuckin seized that night"
2. seized
It's basically like "pwnd" or "owned". Yell it when someone trips down a flight of stairs, or something.

Alledgedly from Halo.
Primus: *falls down stairs*
Secunda: Seized, asshole!

Primus: *is pushed down stairs by Secunda*
Secunda: Managed to seize ya!
