Grandma's Rose Garden 

An old lady's bung hole aka ballon knot.

Where's grandpa?

Not sure. He said he was going to tend to Grandma's Rose Garden.

I'm going to throw up.

Grandma's Molasses 

The worst type of diarrhea imaginable. It wants to come out but it's too busy becoming an awful mess on the inner sides of your ass cheeks, and will not let go.

I'd really love to hang out with you tonight, but Grandma's Molasses has been plaguing me all day and it just won't end!

Grandma's Chicken Soup

The best inside joke ever created. It's derived from Friends, and isn't necessarily meant to be dirty, but comes up like that anyways

Person1: I really like pie. What's your favorite food?
Person2: Grandma's Chicken Soup...

Grandma's on the boat! 

1. A slang term for when a member of ones social circle engages in an act that they would typically be unwilling or unable to participate in due to various limitations.

2. An ironic expression intended to celebrate rowdy behavior by juxtaposing that behavior with the behavioral tendencies of the elderly and enfeebled.

Prsn1: Lets go into town for a late night pub crawl.
Prsn2: Okay, but you know I can't handle alcohol quite like I used to...
Prsn1: Grandma's on the boat!

Grandma's Tux 

A grandma that ties her saggy ass breasts in a bow tie.

Grandma's Tux was quite elegant, despite the fact of these corroding breasts to be black with rot.

I ejaculated all over my chickens the first time I caught a glimpse of granda's tux behind her shed.

grandma's fuck cheese  

When a young adult has sex, usually in porno's, with a mature woman (60+) and licks her vagina that hasn't been shaved nor cleaned. This creates a foaming substance, almost like cheese, where the young man takes it and shoves it into her anus, where the cheese like substance is used as a lubricant.

"Yo dude, Jack played with that grandma's fuck cheese last night. Eck!!"
