I do encourage people to let go sometimes and experience life on the weird side. 
It's way more fun than always trying to stay within "normal" social behaviours. As long as you respect other people and their space, you have no reason to constantly be watching what you say and do.

Seriously, ask any of my friends and they will tell you I make weird noises, talk with no filter and sometimes talk with no sense. But, I tell you, the times I have to pay attention to my words and actions, it is physically far more draining and I'd rather just not. 

SO what I'm trying to get at is: just go crazy sometimes (but like, dont hurt anyone or thing)
