Dude, same here! It's bad. I think incel lingo has taken up a large portion of my brain tbh.
One time I was talking to my 60 year old coworker about height, and he doesn't know what an incel is so I figured it'd be safe to use our lingo around him. So I said "Yeah, if any guy is below 6'0" that's considered manlet and it basically never began for them."
And one time I was with my friend at a bar and he saw a Stacy sitting next to a Chad and laughing with him. So my friend said "Bro, do you think I could steal his girl if I make her laugh?" and I said "That's a giga cope. There's no way she'll cheat on her bf with you just because you made her laugh."
