A feeling of restlessness made obvious by the rapid twitching of one or both legs. Often occurs on a Friday afternoon at work as you begin to start thinking about hitting the pub.
It's 4pm on Friday and this disco leg is driving me crazy! Time for a beer!

When you have been out all night dancing and the next morning you suffer with sore legs, knees and joints....causing you to limp.... then you have disco leg.
Looking hung over and limping.... "He has disco leg"

Needing to pee with urgency. So called due to the twitching the leg does.
