When a man fails to angle his penis correctly whilst in the seated position on a toilet leading to a stream of urine sneaking out from between the rim of the toilet bowl and the underside of the seat.

A rarer yet significant mechanism by which a man misses the bowl, often going unnoticed until clothing is fully saturated.
"I had to go home because the back of my legs were drenched by my own sneak stream"

"If the guy before me hadn't been wearing headphones and browsing Instagram on his phone, perhaps he would have done more to prevent his sneak stream flooding this bathroom"
