Well, hello, RhubarbCommander, and what a fascinating life you must have led. Please tell us more ...
No sooner had I put "An exaltation of larks" away after posting in another thread, than I'm at it again! Here's a couple or three relevant collective nouns for this thread:

- a herd of harlots

- a mews of cathouses

- a concatenation of orgiasts.

Sorry, Jackie, I couldn't find one for 'gutters' but I'll keep trying.
