Big Sean -- Gobbledy Gobbledy G-Gobble Gobble

Tippy tow Turkey Day ... Big Sean's giving back big time this Thanksgiving, handing out more than 650 turkeys to the needy in Detroit on Tuesday ... but stop, the rapper also made it ham-mer time.

In addition to the turkeys, we're told Big Sean gave away more than 100 hams to the Metropolitan Detroit Area through his charity the Sean Anderson Foundation. Mike Epps even stopped by to help!

All told, the food is expected to provide roughly 30,000 meals for families around the city over the next 3 days.

Now pass pass pass pass pass pass pass the gravy.
