According to one of my favorite sources of information, Urban Dictionary…:
CLM: Career Limiting Move

Something that you do at work, that will get you fired, or end your career very soon.

Cut to scene at work this Monday.

CLM #1
Failure to toggle quickly enough out of Lexulous during pre-Thanksgiving Day at the office

CLM #2
Boss: “What games are we gonna pick for this Bowl Game promo?”
Me: “I dunno. We want to go early but what is the “Mountain West” division? The “WAC”? Wha – teams like from SPOKANE or somewhere play in those right? FAIL.”

(Boss is from Spokane).

Happy Thanksgiving – here’s to a job I not only love, but have! 😀
