Weird sayings

I was talking to my sister about this novel we're both reading and I was like "imma deadass drop kick a bitch if they fuck up this story", and my mom just looked at us like we were crazy and asked how do you dropkick someone and told me that's not proper English we're just making things up at this point.
She hates when we say
"It do be like that"
"That (gender) is so fucking rude looking that fine"
"Aight bet"
"Fuck that tea is hot"
