the act of urinating in an inappropriate/unnecessary location whilst participating in anti-social behaviour
i.e:

Man 1 - Are you going for a piss?
Man 2 - Yeah, why?
Man 1 - Do you want a regular piss?, or a FUN PISS?
Man 2 - ... a Fun piss clearly..?

(man 1 takes man 2 down a dark alley, into someone's balcony area of a hostel)

man 1 - Piss there

(Man 1 starts to piss whilst a dirty mongrel walks into his stream)
