The act of a yawn fart in which a person farts so another person farts as well; like a yawn, this particular fart is contagious (in a voluntary manner).
I enjoy a good yart now and then with my husband, but he does not.
yart is term that can be used for many different things. It just emphasizes something that is happening and any emotion. (it is easier to show in an example)
This bitch is getting on my nerves. Imma yart that hoe.
