hysterical Korean bitch. Taegugirl

How I miss that raging Oijin
how I miss her big round head.
She went back to South Korea
and I need her in my bed.

OJing

The opposite of JOing. The feeling of regret that sometimes comes after jack/jerking off. Often followed by rash actions of desperation, for example murdering your ex-wife or singing R&B songs from the 70’s.

Dude 1, “What’s the matter buddy?”

Dude 2, “I just JOed, now I’m totally OJing.”

Dude 1, “Want to sing Love Train?”

Dudes 1&2, “PEOPLE ALL OVER THE WORLD…”
