Get the dutched up mug.
When your friend hands you the bong even though it's pretty much kicked to the point most wouldn't even bother to hit it, but your mama taught you not to be wasteful so you torch that mother fucker until the ash is white as snow.

Comes from the stereotype that the Dutch are thrifty.
"This is beat."
"I'll be the judge of that."
"Alright, dutch it up, man."

To Dutch someone up is a verb describing a sexual act, with the ability to carry it out exclusively being limited to people of Dutch origin. Although closely related to touching up, the feelings resulting from being Dutched up by someone are notably superior. It is also worth mentioning that the unique skillset that constitutes a session of Dutching up cannot be obtained by anyone other than the Dutch. Side effects of Dutching up are inevitable, and include experiencing an immense, marriage-inducing love, combined with a feeling that you have found your soulmate.
I got Dutched up yesterday, and now I'm never going to be single again.

Thirty years ago my friend told me he was going to Dutch someone up, and now he has 5 children and a happy, everlasting marriage.
