Just for funsies

Just for fun.

I'm going to do this reading just for funsies.

just lose it

"Just lose it" means literally
"Lose your mind" or "Go crazy!".

"Just lose it, oh baby."

Just... yeah

Usually used as a desperate, yet subtle plea for attention when you're feeling horribly, horribly depressed. Is usually used to negate the statement "I'm fine" after someone asks if you're okay, in the hopes they'll get the hint and ask you what's wrong. Or, at the very least just pay attention to you or try to help you feel better. But for whatever reason, it rarely works. Either the person you're trying to get attention from doesn't get the hint or doesn't want to get involved.

Person A: *visibly upset*
Person B: Are you okay?
Person A: Yeah, I'm fine.
*pause*
Person A: Just... yeah. I'm fine.
Person B: Ok cool. *leaves*
Person A: God dammit.

Just a friend

Now that Adrien is here

GO TELL MARINETTE THAT SHE IS NOT JSUT A FRIEND

Adrien : Oh Marinette she is just a friend

that just went

"That just went" is another way of saying that something was hot. Or that something went perfectly with the rest of the sentence in which "that just went" was used in.

Travis: Oh you just mad I'm styling on you. But I ain't even gonna go wild on you.

Brian: Yo that just went!!!!
