Hot On The Job. This is a state a person can be in after receiving horny text messages or maybe even messages via secretly used chat programs whilst on the job. It can also be used when u get hot from that sexy office milf from the sales department or the extremely dumb, but hot, intern at your department.
Q: "What are you hiding under your desk?"
A: "It's the boner I got from this text message my girlfriend has sent me, she always get's me HOTJ."
Office MILF: "Could u help me sorting this problem out?"
You: *Looking down shirt* "Yes, I could but you only get me HOTJ right now."
Office MILF: "I get you what?!"
