in the past was a slang about women's genitals/women considered sexually,but now it got a whole new meaning
the word now is to refer a loli vagina on portals like 4chan or twitter,it means the same is with "UOOOH" and a crying emoji,and users of that word try to interpretate as "cute and funny"
Josh: i like cunny UOOOOOOOOH ð
Nina: oh god she is so cunny UOOOOOOH ð
Bob: get away from me pedos
