The examples need cleaning up, too. I smell note a lot of ZCEs.
"It's Occam's Shuriken! If the answer is elusive, never rule out ninjas!"Uncle Phil taking on the blue-collar job of plumbing then exposes his buttcrack because his pants cannot cover it while he works is a straight example of the trope. No changes needed.
Right, the fact that some of the examples aren't even labourers, but just anyone showing their arse crack suggests that it really isn't a trope. For pity's sake, I forget to pull my pants up half the time, too, but I wouldn't say it's a trope. It could also present some Unfortunate Implications that labourers can't afford fitting trousers or are forgetful.
however.... Plumbers/builders show their arse crack? Only thing I could see to make of it would be maybe aversions when someone who lives there walks in and starts talking to the plumber like they're a parent/ friend/ at least acquaintance because they are just bent over, not showing a crack, and then discover they're actually the plumber/ whatever... maybe. Actually, no, not really.
I say toss it, or if not really possible, make it clear that it's a Played for Laughs Stereotyping Trope, and clean it up.

OH MY GOD; MY PARENTS ARE GARDENIIIIINNNNGGGGG!!!!!Do we even need the gender-neutral language? This strikes me as an Always Male trope.

Forgive me, but I would prefer an even more neutral definition for this trope. I like 39 except for a couple little tidbits here and there. This may be an improvement or even worse. But here it is, nonetheless.
The Plumber Crack gag is a classic comedy staple. It is a situation in which a plumber or other blue-collar worker of similar ilk bends to do some task and exposes their butt crack in the process to onlookers.
Common stereotypes of the Blue-Collar worker are their apparent lack of hygiene and personal fitness. Keeping in mind the principle of Show, Don't Tell, the (usually) overweight and hirsute character bends down to take a look at something, and their pants fall or get pulled below their waistline.
The Reaction Shot of the other characters is typically Played for Laughs. Characters are often far more disgusted by the sight than similar sights of "Mooning". Another similar trope is Wardrobe Malfunction.
Same message, a little cleaner, a little more neutral. Maybe it takes too much away tho... hmm.
