Harden The Fuck Up

Used to tell a weak person or persons that they have become far too weak, and to prevent further embarrasment to the human race, they must Harden The Fuck Up.
1. I see that you are on the side of the road with a flat tire. What, you, a fully grown man can't change a tire yourself, and you're waiting for a tow truck? HTFU!

2. "This is Michael. He can't go on a family holiday without bringing his portable gaming console. HTFU, Michael!"

"Hang the Fuck Up!" the cell phone correct version (especially appropriate for vehicular maladiction) of the well-established STFU.
"HTFU and DRIVE!" Ted shouted at the smugly self-absorbed yuppie soccer mom who was toddling along the freeway at 40mph in a van filled with children while simultaneously sipping her non-fat-non-dairy-decaf frap and babbling away on her cell phone oblivious to the furious world raging around her.
