(this is the 2018 version, I have made a previous version which is now outdated)
1) A popular form of insult, using the following format:

Step one: choose a start ex.: "Get outta here, with your" or "look at you with your" or "get your".

Step two: insert the most freaking random object or thing that comes to your mind. ex. solar system, potato, palm tree etc...

Step three: use one of the following endings (these are bleeped out): looking @ss or head@ss. followed by "outta here".

2) when someone is saying a good insult

Note that roasts used to be much more well thought out, and I am very disappointed of what roasting has become.
1)
some person:

some other person: oh yeah, well look at you, with yo grapevine looking @ss, get yo monkey head looking @ss outta here!
some person: please leave, nobody likes you

2)
