Sister Boy

A feminine, homo-type of a male. Used several times in the movie "Tombstone"

Curly Bill, Ringo and their Cowboy
entourage form a block in the center
Rows while BILLY BREKENRIDGE, Behan's bespectacled, slightly
effeminate little Deputy makes his timid way down the aisle,
looking for a seat midst the off fist-fight and yelling match.
2 cocky young Cowboys, BILLY GROUNDS and ZWING HUNT, call out
to him:
