wild-a** guess
Actually, I think WOW's deduction was more of an EG than a WAG and, since he was right, he didn't end up with any EG on his face.

BTW while I have you in the mood, de Troy, are there any particular rules governing the construction of acronyms?

For instance, a hyphenated word like "wild-a**" accounts for 2 letters in WAG whereas the acronym NORAD squanders the first 3 letters on the first word alone. What gives?

Acronyms have become such a ubiquitous part of daily life, surely we need some rules to bring some order to the universe (OTTU).
