The act of two people scissoring but instead of stimulating each other a fart is expelled into the other's anus. On rare occasions a shart is transferred from anus to anus making it a blomster royale. On occasion the unintentional act of a space docking shart will occur.
That blomster from the other night left me feeling bloated for days.
I was trying the blomster for the first time with Kevin and he sharted right into my vagina like a total Chad
Wow, mate, look at that bird over there with the gorgeous hair. I'm going to ask her for her number. (Lady turns around). Oh fuck it, she's a blonster. Mission abort!
