Some wrestlers do that. Mostly indy guys who've been in for more than a year or two but less than ten. But I've never met a non-worker who was quite that sad.
It's really funny when non-fans who are friends of fans who use this "real life smark talk" start using it too. I know a few people like that.
I know! A co-worker has grossly mis-used my aforementioned "mark-out". Examples:
Referring to a faulty RCA Home Theatre that was returned. "Yeah, man, they aren't well made. One of these came back, marking out, losing power."
Telling a third co-worker about the lack of work they did a night before I was due in the following morning. "Look at this mess! Brian's gonna mark out!"
HAHA. You should continue to fuck with them. Tell em to job is to get the customer to buy the extended warranty.
