When you go to pee in a public bathroom, notice it's empty of other patrons and take a dump instead.

I had a tortoise head! The girls were all chatting and I had bit of old tissue in my pocket, so I dived in the hedge and turned one out! It was the perfect plopportunity.

When you have to shit so bad but you can't because you are in an inappropriate shitting venue so you hold it with all your might. Finally when you get home you either can't shit or you have a shittack because you held it so long. not a good poo. this is a missed plopportunity.
Uh dude, my stomach is killing me...I really had to shit before but alas, it was a missed plopportunity
