1) A gathering/celebration of why our not special or no one cares 2) Everyone/everything has a date of creation, hence the birth day. 3) Just another bullshit holiday for the already barely-getting-by-on-my-shitty-pay-month-to-month pay checks so to become pressured to celebrate the many and continue to make those in power richer (why they sleep) and you go back home to your programmed existence.

Having sexual intercourse with a woman while she is giving birth. This could or could not result in possible intercourse with the new born. It must take place after the woman's water has broken and should be celebrated as the first birthday present the baby receives.
"Dude, whats wrong with your baby's face?"
"Oh, after the Happy Birthday I gave her, her mouth might be a little off."

"The baptism was okay but I felt awkward being the godfather and the one to give her and her son a Happy Birthday."
