Boglegs 

To become "boglegged" and indeed have "boglegs" you have to spend a good deal of time on the toilet, after a while the blood flow to your legs is restricted and as a result you get hyper pins and needles and your legs go all Mongy and you cant walk when you stand up.

I was found on the floor of the toilet with me cecks round me ankles and widdle on me stomach as I stood up when I had boglegs and went arse over tits.
