|1.||2 hour pants|
If you have a shower in the morning and put on clean pants you will probably have those pants on all day & all night.
If you have a shower after tea and nip down the pub those pants have only been worn for a couple of hours so when you go to bed become "2 hour pants". There's nothing wrong with putting these back on the following morning!
I don't need clean underwear today love. Ive got some 2 hour pants here!
