Unintentional Self-Fulfilling Prophecy

Okay listen up, buttercup. This meme shows a dude making a general statement about girls having ego problems. Then, another person immediately responds with a huge, angry, and defensive rant trying to prove the dude wrong. The joke is that by reacting so strongly and defensively, the second person totally proves the first guy's point without even realizing it. You probably do this sometimes too when you get called out and start overexplaining things, making you look exactly like the person you're trying not to be.
