Snoop Dogg Surprises Fans on Random Party Bus, Dances & Smokes

Snoop Dogg 's still living a young, wild and free life ... getting down on a party bus -- one he wasn't invited to board in the first place.

The rapper posted a video on X Saturday night ... saying he just crashed a random party bus -- and he hopes they all enjoyed spending about a minute with him before they continued on their merry way.

Check out the clip ... no context here, but Snoop seems to just appear on the vehicle -- totally shocking the partygoers aboard the bus.

From the riders' reactions, it seems clear this ain't a set-up ... 'cause there are a series of shocked shrieks and 'WTFs' heard when people notice the rap legend.

Snoop dances with the shocked fans ... before lighting up what looks like a blunt and smoking away as his own song "Ain’t Nuthin’ but a G Thang" blares over the speaker.

It's a pretty short interaction -- with Snoop hopping off the bus after about a minute instead of continuing on with the group to their next locale.

Snoop seems to be just about everywhere these days ... hanging out at his wife's strip club , popping up on TODAY and even taking on a major role at the Paris Olympics over the summer.

And, right before Halloween -- when most people play make-believe -- a lucky group of fans got to see the real D-O Double G!!!
