Listen here, Zac. The meme is addressed to "Mom", a representative parental figure of - let's assume - Gen X. Now, Gen X was not really into anime, which is the butt of the joke. They weren't a bunch of weebs and probably also refer to group of the Japanese warrior class as 'samurais'. HOWEVER, they called lots of little bricks 'lego'. It was Millennials that started calling them 'legos'.
So, I'm pointing out the hypocrisy.
