look up any word, like blumpkin:
 
1.
1. An appropriate or favorable time or occasion to defecate or shit.
2. A situation or condition favorable for attainment of taking a shit.
3. A good position, chance, or prospect, to use the toilet to void excrement from the bowels through the anus.
The break during our staff meeting afforded a shitportunity.

During our road trip, we frequently stopped to get gas, food, and of course, to take our shitportunity.

If I miss my shitportunity this morning because the client is late for our meeting, I will be clogged up the rest of the day.
