I have a friend who is kind of a jackass he goes to parties and acts stupid (starts fights, creeps out girls or sometimes even gets drunk) and then gets kicked out. The thing is hes the one who takes me to these parties. However i get wierd looks because i assosiate with him and therefore get grouped into his category. Which im not.

When he gets kicked out what should i do?

Should i stay with him? Should i pretend i dont know him that well? Should i stay at the party and just make an excuse for him like "i think hes just a lil smashed"? Do i need to just get new friends?

How do i handle this?
