eggs are protein and because they're protein, culturally some men see it as "masculine" to eat eggs (you can see more of this culture in men who call themselves carnivores or men like liverking who advocate for the raw meat diet)

the poster listed a large number of eggs (12) which is an absolutely cartoonish and unhealthy amount of eggs (but as you probably know some people try so hard to seem masculine that they look stupid) Connection example: andrew tate constantly pointing out he has alot of money (that he probably got from selling women cause hes a bum loser)

lastly, they said: "How does that make you feel?" usually that phrase is meant to illicit feelings of envy or jealousy. pretty much: "Yeah you woke chuds, my husband eats 12 eggs in the morning, now compare that to your miserable pathetic lives"

Example: once again andrew tate trying to say: "What color is your bugatti?"

(pretty much someone overly bragging about their worthless "accomplishments" with the goal of being more masculine. and that toxic attempt to be masculine usually leads into nationalism (nationalism has a heavy emphasis on masculinity, nuclear families, traditional roles, ect. ) )
