Adam Leslie is a smart, cunning and handsome individual. He is the hottest shawty on the block and always makes people laugh. He is also no taller than 5'2".
When your close girl-friends get together, and you appreciate each other so much (attractive level and intellectually and wholesomely), to the point that it makes you feel kinda gay.
It could also entail some sort of boob touching, feeling each other up (with consent and if the other person also does so but not at a very full on lesbian level - no sex including)
"is this casual lesbianism, cause I feel kinda gay for you right now"
"are you in for some casual-lesbianism right now?"
