13th grade

Any community college, especially Harrisburg Area Community College (HACC). It's basically the same exact thing as high school, except it's easier and people around you are generally not the sharpest tools in the shed and give even less of a shit than they did before. See also the bomb diggity.

Looks like Joe has to repeat 13th grade. I guess he just couldn't HACC it.

A creepy uncle that touches little kids.

Friday the 13th

A day when everything fucks up and goes to totally opposite of what it usually does.

A time for hockey masked wearing pyschos to slaughter unsuspecting victims.

"Its Friday the 13th!"
