The weed that will knock any veteran smoker on their ass, and make the rest immobile. Smells dank, looks dank, and tastes like blueberry. Gives a very unique brain high coupled with a great body high.
- "I had been smoking on medical trainwreck and hindu kush for a month, and then when I went back to the 253 my buddy hooked me up with some blueberry yum yum and one joint knocked me on my ass for hours."

- "Me and my friend shared a blunt of blueberry yum yum and we couldn't finish it, and my friend couldn't move."

Type of Weed made popular by Ludacris, it is a slightly hashy weed with a fruity taste simmalar to blueberry's. Better stuf (stuff *real* growers smoke) tastes more simmilar to a rough black berryish taste, also the plants are not as pale in Ludacrisis video those are probly Skunk or Dutch because blueberry forms darker shades of green/blue as it gets closer to where they bud.

A name often given to a female of Persian descent that is good in the bedroom. Not all Persian ladies qualify but most would fit the bill. Most of the time if you see an exotic woman that you would like to escort to the bedroom, you are most likely craving some "Persian Yum Yum"
Heraldo: "Dude I need a change in my life sexually, something to spark it up a bit..."

Neema: "Bro you need some Persian Yum Yum."

A Shanghai Yum Yum is a semen-filled doughnut.

The Shanghai Yum Yum is typically achieved by cutting a small hole into a plain doughnut before a willing female masturbates their partner into said doughnut (usually while stimulating the prostate with the deft use of a little finger) thus filling it with jizz. The female will then immediately eat the Yum Yum as it is best served warm.

A sandwich that can only be called such when created on Thanksgiving Day consisting of every ingredient available during one's Thanksgiving meal.

The bread must be a dinner roll from the meal as well.

If the sandwich or any similar food creation is created not on Thanksgiving Day or not following any of the specifications previously mentioned it is simply a Thanksgiving Sandwich, and NOT a Yum Yum Boat.
I can't wait to make a Yum Yum Boat on Thanksgiving.

Person 1: Dude, I'm making a Yum Yum Boat
Person 2: It's the day after Thanksgiving, that's not a Yum Yum Boat, that's a Thanksgiving Sandwich!
Person 1: Damn!
