The slow process of one male turning into a beta-male, or a "pussy". This process usually takes about a year, but it can take up to 3 years to take full effect or down to 1 week for the process to go on.
Mom: "Son, what has gotten into you? You don't even go to the gym anymore. You're really turning into a beta-male."
Son: "I know, and I'm sorry mom. It's the pussification getting to me after my girlfriend broke up with me."
