To masturbate. Means to do it after school. But has evolved into a general term to wank it.
Is tenth period because the typical school day is 9 periods.
Bruh I got to crank out a tenth period. I'm so horny.

I can't wait til the last period, ninth period, ends. So I can wank my dick in tenth period.
