Comment on a person's behavior of liking their own posts on social media and how it might make them look.
Joe, Joe, Joe...yah gottah STOP 'liking' your own posts. Is that the third or the fourth time TODAY?! It makes you look stupid - and although I realize it's the ONLY way you are going to get ANY 'likes'. But still...you don't want to look THAT stupid do you? Well...never mind.
