Invitation shorts?

So I have these big laggy plaid pajama pants I like to wear to bed sometimes. They're comfortable. But when I wear them my SO knows he's not getting any that night.

I also have these shorts. They're his favorite shorts. They're the dye comfy cotton shorts that are more like loose boy shorts and my cheeks hang out of them. When I wear those it's a guarantee my SO will get some.

So today I got out the shower and pulled my shorts out of my drawer and put them on. He comes back upstairs and takes his hat off and takes his shirt off and jumps in the shower. His response 'uh oh You have on the invitation shorts!' lol

Anyone else have an outfit to let their SO know it's 'that time'?
