If I had, had a big party it would be shit shit on the walls
That being said, i have had luck with bicarb and water. Make it into a paste and with a soft scrubbing cloth apply and scrub scrub scrub
Toothpaste also works too
bicarb and water or bicarb and vinegar, if sticky stuff use oil based stuff veg oil, mayo etc if it is actual shit disinfectant first then depending on wall paper or paint bicarb and vinegar for stains good luck with that
