obkb
It’s like saying 'ok, be cool, bye' but with more sass and less brain.
My mom said 'ObKb' when I left for school and she was mad I didn’t do my homework.
My brother said 'ObKb' when I took his video game and he looked like he wanted to kill me.
My teacher said 'ObKb' when I messed up the test and I got a D.
