When a girl gives you a blowjob while wearing a beer can baseball helmet and hands you the straws to drink the beer during the act. Bases loaded optional...

It was the bottom of the ninth and I was noticeably depressed because my team was losing. My girl wanted to cheer me up so she loaded two natty lights in her beer helmet and started grand slammin me

Grand Daddy Duz 

It’s a combination of being a grandpa, professional shit talker, and a whole lot of headass.

grand canyoning

when you convince someone that they've done something or gone somewhere (like the grand canyon) by fabricating a memory of it by telling them things you've done that you've told them about before

an example of grand canyoning:

person 1: dude do you remember when we went on a trip to florida?
person 2: no i've never been to florida
p1: remember? the lady at that gas station said they didn't know what our state was (happened to p1, but not p2)
p2: oh yeahhhhhh!! i remember that now (was told that story by p1 years ago)
p1: see, we went to florida
p2: yea i remember

When you fuck six girls at once by sticking your dick in one girls, your tongue in another, and your hands and feet in the pussy of the four remaining girls. Note: there will be a lot of moaning and it will look like you have girls growing off of your limbs.
