Literally dumpling in Chinese, figuratively your down as chick or guy. Usually in secret, your momo is not your friend or real partner. Your secret non-sexual lover. Both parties are Momos and must be in committed relationships to be called so.
You go to the gym and work out with another person of the opposite sex. You workout, text, email and talk with minor flirting but there's nothing going on. That person is your Momo.
