Because they were trending on tiktok and he'll never admit he lazily tries to follow trends. He even referred to a couple as "the tiktok tumbler" or whatever.Why does Jack buy these fucking mugs my God. He doesn't go anywhere and when he does he buys a drink. I have some nice mugs for driving but home, office etc I want a real glass. I suspect the spill proof is a big sell for Jack. Much like kids need sippy cups.the test was retarded and he's such a sloppy gross animal.
