2.
The process of celebrating the birth of a baby. Traditionally taking its name from the Christian baptismal rite, during which the head of a baby would be wet with blesed water, the phrase now commonly relates to the consumption of large amounts of alcohol as a celebration of the new arrival.

The actual process of wetting the baby's head is far more fun before the baby is born.

Bloke 2: We're here celebrating, to wet the baby's head.
