Huck Finning

Referral to the practice, by individuals of either gender, of loosely rolling both pants legs up one to two rolls until the cuffs are between the knee and ankle, so as not to drag the ground.

We were Huck Finning so that our pants wouldn't get wet while wading through the water.

That's cute. She is Huck Finning today and it looks good with that outfit.
