Get the fart facemug. 
A person who's face reminds you of a fart. Usually, they have round features, like round cheeks, round chin, round nose, plump lips etc and thick facial skin. Typically they have shiny, "dewy" (careful not to confuse with greasy) skin but in a gross way and it's like a sweaty butt. When you see them, you imagine their breath smelling like boiled eggs and a fresh can of roasted peanuts.

Person #2: Nah, she has a mega fart face. Look at her round face and round cheeks, looks like a rank fart.
Person #1: True
