In the gay world, more specifically with drag queens or trannys, to look bricky in a drag outfit, means to still have a quality that presents you as a man (ie. muscular arms, big hands, or walking like a dude). The opposite of bricky would be fishy
#1 - "Girrrrl, Jorge showed up at the club wearing this Viven Westwood V-neck sweater, and I think they had shoulder pads, and it made him look bricky"
(Alex and Liz waiting to get in the club standing passing a brick wall)
Alex: Liz, do I look bricky tonight?
Liz(turns to the voice): Girl, where did you go? Girl...(she tries to feel for him)
---they pass the brick wall
Liz: Girl, I lost you for a second passing that brick wall.
