used to describe someone who you think is amazingly attractive, and that you'ed like to be with, or what you want to use to exspress your feelings toward that inperticular person of whom you are attracted to.
+I'm Sure Every1 has their own opinion on the matter/subject/topic !!!
and it's good that we all have ower own opinion or SEXY wouldn't mean as much to us and we couldn't use it to express so much affection and love for who we either are just attracted to or have loving/affectionat feelings toward.
