👉 SFL stands for "Stupid Fucking Leg." It's a term coined by comedian Kevin Hart to describe a situation where someone has been caught doing something they shouldn't be doing, like lying about their age and being mistaken for a celebrity.
Here’s an edgy or unsettling example sentence using SFL: Kevin said: "I'm not sure I trust his credibility." Hart replied: "Yeah, it's all fake. He said he was 29 but now he's 30."
