Ohh I see you're missing out on the fun side of "legit"
Because this is what I am thinking when somebody says "legit"
Also isn't it some kind of skateboard term from the 90's?
"Broooo that 720 was legiiit 🤙"
"Like" is a critical one for me. As a non native speaker it's just so tempting to use. Like in the above example. I would have 100% introduced that direct speech with Like
