When you scrunch up your lips and the muscles between your nose and your
upper lip to create a
shrivelled lip, creating creases that makes it seem like you have two little moustaches/whiskers above your lips.
*resembles somewhat like a posh
troll face without the open mouth smile.
When you walk up to a friend and you
eye contact. You greet each other with the “
moustache face”.
When your friend says
something and you want to be troll or suggestive, you give them the “moustache face”.
