Trailer-radar. The ability to tell from movie trailers if a movie is bad or not.
'Robin Hood' with Russell Crowe looked good on paper, but when I saw the trailer my traidar said avoid this flick like the plague.

The ability to find girls who are complete train wrecks. Usually they are hideously ugly and/or have severe mental problems. They are easy prey and a guarantee hookup.
Max uses his traidar at bars to guarantee he gets some lovin at night.
