genitalia that is sizeably much larger than an "average-sized clitoris", and yet still smaller than an "average-sized" penis. it's somewhere in-between.

individuals labeled female at birth, and who have been on or are currently taking testosterone, often-times have such genitalia.

the longer word for such genitalia could be "clitweenis", but we'll just call it 'tweenis for short.
once i started taking testosterone, my clit definitely increased quite noticeably in size. now it's a 'tweenis!!!

Portmanteau word, made up of "tiny", "weiner", and "penis". It's an insult similar to calling someone a "dick".
Stop being such a tweenis, dude!
