trolling is also used in gayspeak to mean something somewhat similar to the fishing term. essentially, it's what you call it when an ugly, fat, and/or old gay man is out cruising or trying to lure some unsuspecting gay male into some sexual encounter. in other words, trying to hook but often failing miserably due to physical or aesthetic shortcomings.

granted, it's not a very nice term.. as it requires that one must be a troll (usually a subjective term, but often means fat, ugly or old gay man) in order to be trolling. i suspect this term was developed by the oh-so-precious and flippant bitchy, vain gay men who complain about getting hit on by men 20 years older than they are. but there's a word to describe what they do, as well..
