You know you have reached the esteemed rank of expert manipulator (BS’er) when, on a bright SUNNY day, you and a friend walk through the door together, he holding for you and someone says
“How is the weather out there”
You respond
“Raining cats and dogs”
And your friend looks to see if it is.
An XMTXYL is someone who borrows your watch and tells you what time it is.
