look up any word, like timebomb:
A Questionable Hook-up. A person you wouldn't or shouldn't hook-up with.
A QH is someone you kissed (or hooked-up with) that you probably shouldn't have. Furthermore, if someone wants to hook up with you, but finds out you hooked up with someone they would question, now they are questioning whether or not to hook up with you, because of your judgment in hooking up with the person you did.

Sexually turned on feelings that are like the allergic reactions of oversensative skin and heart palpitations caused by Q.H. particals coming down from the atmosphere. These particles form when Q-RAYS charge Hydrogen Ions and sink to the earth where we breath them in.
Hey baby, I got the Q.H., come on over and take care of it.
