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."

Happy Thanksgiving - here's to a job I not only love, but have! :D
