kneesie 

When two, sitting, people are flirting by touching knees usually under a table. Similar to footsie but is better done while sitting side by side or kitty corner, and is less likely to cause outbursts of laughter. Also the recipient often wonders if the kneesier is doing it on purpose.

Q: Was that creep playing kneesies with you too?
A: Yes, my knee will never feel the same.

booze knees 

Incredibly sore knees on the morning or day following a night of moderate to heavy drinking. A dull, but intense pain in the entire knee joint; kind of like a headache in your knees. It can be so painful that the sufferer can be almost bed/couch-ridden for most of the day.

"Honey, I can't do the dishes this morning. I can't stand for that long due to a mad case of booze knees."
