Collective urine puddle. Where running streams of random people's urine meet.
Commonly sighted at music festivals, this large pool of urine is a result of streams trickling from demountable toilets.
Often hard to distinguish from water and other safe liquids due to contamination and discolouration from dirt, alcohol and other festival matter.
John: Look out bro! (grabs his friend'd arm)
Andy: What? (looks down)
John: Gee, that was close. You almost stepped in that large puddle of conglomourine.
Andy: Thanks bro.
