If a woman sent a message to Fridman asking him to give them bigger breasts, we'd feel a little sad that they were unhappy with their appearance, but we'd understand. When a man does it - and talks about a girl in such a disrespectful manner - he gets no such understanding. To make things worse, from the pose we suspect they're boyfriend and girlfriend. Why does she put up with him?
Fridman has given him the benefit of the doubt. Surely nobody would be so rude as to describe their own girlfriend in such terms, so he must have been talking about himself. Now, he has an enormous pair of breasts. This is what it means to truly make a boob out of yourself on the internet. At least he can ogle himself in the picture now instead of worrying about what she looks like.
