Water Moustache 

I invented this word over a year ago. But to me, it has already existed for quite a long time, even before I was born. The thing existed but the word didn't. Well it just did.

Basically, it's just sweat that forms on your upper lip. Or maybe even on your lower lip. I first thought about this when I was eating atva friend's house. Her sister cooked something spicy and while eating it, sweat formed on my upper and then that was when the term, "water moustache" was born. You're welcome.

John: *slurps noodles* Man, I can't do this anymore. It's too hot.
Jim: Yeah, maybe you should stop. You're starting to get a water moustache there.

Moumou/Moustache

Moumou/Moustache isn't an ordinary cat. Looks more like an otter than an otter. A fucking cat-otter.

Also very cute, but big red flag : likes to sit on you and stares at you for hours while you're sleeping to establish dominance.
Might stare at you from every corner and places you couldn't even think of.
Barfs to show his affection.

Omg, my cat barfed again on my bed this morning, he's such a cute Moumou/Moustache !
