argue with your friends in public!
More about argue with your friends in public!
Meet up with some friends somewhere to hangout at such as a food place. Have a few friends meet you there and pretend that you don't want a certain person there that shows up with them and kinda make a big deal out of it but be funny! Pretend that you wanna leave since they showed up! See if people start to stare and ask you if everything is ok!
