Question to Wild Weasel Types

[Caesar 305]

Quick question for all you Wild Weasel historians:

 

I've seen a lot of WW patches with the YGBSM (You Gotta Be Sh*tting Me) motto written on the bottom, but I noticed on some patches, there is a line which precedes YGBSM which reads:

 

"WTFAIDITB"

 

Thinking about the possibilities, am I right to translate as: "What The F*** Am I Doing In This B*tch?" or am I totally off base?

 

Thanks for your time and replies.

I will have to consult my books which are still boxed... but you may be correct.
