Been seeing enough players at 100NL FR that will bet $1 into a big pot and then fold to a raise that I now have an abbreviation for my player notes (see subject line). These players seem to fold everytime they do this... I have no idea what they're thinking. Very rarely I run into a player that will come over top of my raise, so watch out for those, but the $1BFtR'ers are much more common.
