You need some beard oil 

A rude suggestion for a man with a very stiff and pointy beard, one that could pop balloons and pierce skin. The term will make the man question if his beard is hurting people. Often ends up being repeated until the man shaves his beard.

Amy Adam: God Jack Black, your beard is so pointy. You need some beard oil...
Jack Black: Shut up! I like it the way it is! Stop torturing me!
