H.R. could mean a few things. Let me list them.
1. hotel room
2. holiday rush
3. human resources
4. herbal tea
1. what a guy/girl says when they are around adults. "lets go to the H.R." meaning-lets go to the hotel room.
2. if you went to school for at leats a year you would understand this one. What you feel during break.
3. boring people that you call when your $3,000 fridge doesnt work.
4. a nice cup of hot tea. "can i have a h.r.?
"God, I hate blacks and gays, so so much!"
"Geez, Zoe, why do you have to be such an H.R.?"
