Hey! That's my line, lol. whats "tatem" mean?

My best "unglued" story. Was working construction in La [Houma] mid '80's as a carpenter. Had built these huge 30'X40' gang forms for wall concrete pours on the ground. Assistant supt [jerk] told me to drill the wrong side of form for cable and clamps so he could move them w/ crane. Told him that needed to be on end, not side as that's how they were built. He said do as I say, don't argue, just do it! Did it, and when he got the first one on about a 45 degree angle, it came unglued, lol, busted wood every where. He slammed his hard hat on the ground and said it looked like he'd have to go up north [I'm from Illinois] and open a school for carpenters. My reply to that was him running a carpenter school would be like Hellen Keller running a rifle range, lol. He tried to fire me but the Supt was laughing so hard, he just sent me back to work.
