Going down the river Thames 

When you are having sexual intercourse and your partner has an urgent diarrhea, which he/she cant hold and lets go. But being the brave man that you are, you ignore the obstacle and keep on doing what you love the most... (no pun intended)

Bro, me and my sis totally went down the river Thames last night.
Going down the river Thames is my lifestyle.
