heres my latest ones
in estonia we have an energy drink called dynamite and its great for "urine pranks" cuz its yellow
so me and a couple of my friends bought a bottle of it and went onto a bridge and then slowly poured it down to the sidewalk below and the ppl going around it had an awesome "what. the. piff." face on them xD (thank god its a quite cheap energy drink)
and another one with the same energy drink
since we have snow here me and my friend were walking past ppl holding the bottles near our crotch and again poured it down a bit when ppl saw us from behind... it was kinda funny xD
