When you hand someone your phone to add their number, and they instead open venmo and send your balance to their account. Usually happens when drunk at a bar.
Person 1: "how was your night? I heard you met someone at a bar?"
Person 2: "shitty. I tried to get her number but she venmugged me instead"
if you are only partially joking when you say something, jkinda can replace jk. JK + kinda = jkinda
"I'm here, are you ready?"
"I'll be ready in like three hours"
"Are you joking?"
"...jkinda"
