5k holiday family

A family that runs 5ks on holidays

Person 1: How was your thanksgiving.
Person 2: Terrible I'm in a 5k holiday family. Our whole family was forced to get up early and run a 5k before we celebrated.

filthy 5k

Running a 5k and then immediately proceeding to receive oral, leaving your sweating crotch stench all over your partners face.

I surprised my girl with a filthy 5k and she threw up all over my nuts.
