look up any word, like bukkake:
 
1.
The result of anal penetration leading to bloodshed through the anus. The blood drips out of the anus, imprinting onto the wrinkled skin - creating a 'crimson flower'

This can then, if the person so chooses, be pressed against a piece of paper to make a colorful artwork resembling a crimson flower, to put on your fridge or hang on your wall.
" Me and Bob had anal last night... He got pretty carried away and it was so rough I almost got a crimson flower!"
