Mustard flower 

In an instant where you crack an egg just the yolk onto someone's butthole and then pop the yolk leaving a yellow flower shaped puddle

Or when someone has their hole pounded into Oblivion and bloody semen leak from their hole that resembles mustard

I plunged my meat so far into his hole that I left him a mustard flower

Mustard Flower 

When you break an egg (just the yoke) over someone's butthole and then pop the yoke.

Or when one's anus gets pounded into Oblivion and then bloody semen leaks from their hole leaving a mustard type look.

I plunged my meat into that guys hole, giving him a huge mustard flower
