brownie backwash

The melted, soupy leftovers of a hot fudge brownie sundae that was shared by three or more people at a national-chain restaurant.

No one at the table wanted to finish our dessert because all that was left was brownie backwash.

Backwash

The sediment and/or particles of whatever you're eating that ends up in your drink.

William- "Hey Sven, what are those floatin' things in your cup of Perrier?"

Sven- "Just some backwash of water chestnut and sesame"

William- "Why on gods green earth were you eating water chestnuts and sesame seeds?"

Sven- "I.. dont.. know..."

bathroom backlash

When someone in a public restroom (especially at work) gets angry at the lack of cleanliness/maintenance and purposely trashes the place by throwing paper towels on the floor etc.

Co-Worker 1: Wow! Is the janitor on vacation this week? The bathroom on the first floor is a total mess.

Co-Worker 2: Totally! I was so pissed, I was feeling some bathroom backlash so I totally trashed stall 3.

Bulgarian backwash

When you bust in your partners mouth and she secretly withholds from swallowing then proceeds to kiss you letting your cum seep into your own mouth. This act is perform in either deep hatred or kinky love. Either way it makes for a salty surprise.

My toothless bulgarian hooker surprised me with a good ol’ fashioned Bulgarian backwash the other night. Easiest 5 stars I’ve ever given.
