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.

A momo is a man who is very stress-heady who can tend to fixateon one subject and only talk about that , and never talk about anything else.A momo is a man that attempts to make funny jokes, but no one ever laughs at them, because they are lame and unfunny. Also, a momo is the kind of guy that enjoys eating plates full of potatoes alone.
Person 1: "god im so stressed because I can't make everyone understand about different kinds of lightbulbs and I just want to eat some potatoes"

Person 2: "wow, you are such a momo "

A brute machine who talks unprecedented amounts of shit and takes the gerth of any cylindrical object up the ass whilst having a red gimp ball in his mouth.
Mo Mo - "To be honest lads she wasn't a brute!"
Other guy - "She was chronic, she looked like Predator. You're such a Mo Mo"
