a portmanteau, or blend of the words “bullshit” and “meter.” Most commonly referred to as a “pocket bullshometer:” it’s a BS detector. It’s not a real device, (although such an invention would be handy) but rather just the little alarm that goes off in the back of your head when you know you’re being scammed, conned, played,or just lied to. If your bullshometer is going off, rest assured you’ll soon need a shovel and some boots or, better yet: hip waders. Earliest known usage of this phrase was in a customer service inbound call center in Oklahoma City, OK; circa 1999.
“My pocket bullshometer was beeping like crazy during the President’s speech today.”
