Get the Niels mug.
The name of the most amazing guy in the world. He is incredible, smart, fun, creative, and really cute. When you are stressed, he’ll listen to you. He may or may not enjoy smoking weed, drinking beer, and consuming a certain type of “stracciatellacottage cheese.
“Hey I think I have the biggest crush ever on this guy. I dream about him every night and during the day too.”
What’s his name?”

Niels is a very smart boy who can't hold any snapstreaks. He lets you fall but helps you right back up. Conversations never get boring, he can annoy you just because he makes you feel some typa way. He is extremely handsome and very popular among girls. He has beautiful eyes which make everyone stop and stare. He is a keeper, has the beauty and the brains. There aren't a lot of people like Niels wandering the earth. So when you find this rare human being named Niels make sure he doesn't take off.
"Look over there, is that a Niels?"

"Omg look at those muscles, he is so NIELS!"
