My housemate insists on using the word rap

I'm almost at my breaking point. I live in a shared house of "mature" students, one of which, Connor, is causing me immense emotional and physical stress.

The biggest gripe I have with him is his insistance of using the word rap, he thinks we are getting "rapd" by the utility company through the cost of gas and electric (It's true in some ways, we are paying a ridiculous amount), he claims tesco has "upped the rap" through the cost of his favourite monster flavour going from around to a pound to £1.89.

Everything has to be a rap to him. Another member of the house, who's bedrooms are separated by a wall, claims Connor frequently uses the the verb to rap online when hes gaming with his friends - it's often "RAP HIM RAP HIM" or "COME COME I'M GETTING RAPD". I cant even begin to describe how problematic and triggering his flippant use of the word is, if he was 16 or 17 I could understand the lack of maturity but this guy is about 24.

WTF?
