When you go to the bathroom having to take a #1
The need to take a dump makes it difficult to take a piss, which results in going #2
first to allow you to go #1
Often uncomfortable for guys due to the fact that they are sometimes forced to piss sitting down.
I had too much to eat and drink. When i went to the bathroom, i had trapped piss inside of me, so i had to take a piss sitting down like a wimpy girl :(
