I think they put something in my coffee

I needed to print something. So I took my USB drive to the computer where we can print. I become noticeably aggravated. The dialog between a fellow student and I is as follows:

Me: Hey “K” can I jump on that computer and print a few things
K: Yeah, go ahead.
Me: ugh
K: What’s wrong?
Me: Your huge ass USB drive is cock blocking me!
My Advisor (whom I had no idea was right around the corner): What did you just say?
Me: *blush*
