A Jonathan is a clear plastic water bottle of any size filled halfway or all the way with water, stuffed with basically any piece of plastic or paper or dirt you can find and held as a keepsake. You shake it and just bring it around with you.

Walking to a job interview? Bring your homemade Jonathan with you. Funeral? Jonathan's coming with you too.

Some ideas of materials to put in your Jonathan include moldy bread, cardboard from tablet boxes, or anything you can find laying around.

Get the Jonathan neck gaiter and mug.
Handsome. Strong leader, expressive, devoted, guilty of tunnel vision and not letting anyone get in his way of getting what he wants. He has high expectations of others and of himself. Passionate about causes. Sensitive but tries hard to hide it. Loves to laugh and have a good time. Hates drama. Changes his mind over and over until he is sure. Has a temper. Plans for everything, and worries about the things he can't control or plan for. Great guy who others look up to.
Jonathan is a great guy!

Get a Jonathan mug for your cousin Trump.
A guy normally known for his speed and good looks; also known to be a charmer. Jonathan(s) are good friends and the best boyfriends. They are usually of a sensitive nature but are not afraid to use their strength when they need to.
There isn't a time where Jonathan hasn't made my stomach flutter.

Get a Jonathan mug for your mama Sarah.
Jonathan is generally a really nice guy. He is cool, layed back and is always laughing. He jokes around a lot and sometimes can get a little too mean but he is a great guy. He has the looks and has the personality to match. Jonathan is a nice guy but can get a little bit cheeky/naughty at times ;) He is a great friend, a great lover and if you're having a bad day, he is sure to make you smile and forget the negatives.
