Nick Young -- Married Life Is Gonna Be Boring

Nick Young's days of raging and having fun are over ... 'cause now that he's engaged to be married, Swaggy says he's trading in the fast life -- for bingo.

Moments after he proposed to Iggy Azalea, Young shot a video talking about what his life is going to be like after trying the knot.

"I've retired my jersey man, I'm done. I'm gonna go play bingo and cards ... that's my life now."

Moments later, one of Nick's friends poured out some liquor for Nick -- saying, "To my dead homie."

Soooo ... congrats!?
