An effiminate, bisexual or gay male. Height of popularity was from 1984-1986, geographic usage confined between Waterford/Montville, CT to Warwick, Rhode Island. Being "Gayling" had a major following, members of this "group" usually were GQ-fashion victims, shopped at Midland Mall in Warick or Crystal Mall in Waterford.
I was sleeping over Mark's house when I awoke to him going down on me, I mean he went total Gayling on me!
Like the previous definition. Describes a bi-sexual male who looks like a GQ model. Never has to worry about if he's going to get laid, he always does and with either gender! Terminology used in the Southeast CT & RI area back in the mid 80's. Only heard now in a reminiscent way.
Hang out with a gayling and you enjoy the best of both worlds!
