Id ask
What are you.
Then hit her with one of my preloaded racial slurs.
If shes italian i remind her shes only been white for a few decades and is a white n-word
If shes Irish - same thing and make some kind of remark about eating fried chicken and potatoes
If shes russian ill tell her shes a white asian
If its an arab then thats an obvious homerun
If its just some random cac i cant place i just tell them im going to cum in her daughter and make her love me.
If she doesnt have a daughter i'll tell her i have more money then her and tell her she can come to my house to buy dogfood after obama evicts her and her family.
If i dont want to get racial ill play on her low self esteem as a woman and call her fat, ugly or say something to the effect of men will always cheat on her because shes ugly and a disgusting human being.
When dealing with white racist scum, you just have to stay calm and keep the ether flowing.
The possibilities are endless.

What i wont do? Is be the bigger man and walk away.
