The position adopted when needing to pass solids but confronted with a fetid, overflowing and/or urine soaked toilet.
Derived from and identical to the stance of England rugby player Jonny Wilkinson before he takes a conversion/penalty, as in "to do a Wilko"
Commonly used in festival toilets, workman’s portaloos and developing countries.
"Horrid bangers and mash
forced me to do a Wilko"
"Toilet seat soaked in piss? Time for Wilko!"
Wife - "How many times have I told you to put the seat up before you tinkle?"
Husband - "Don't worry darling, just do a Wilko"
