Get the Middymug. 
He is ambitious and kind. He’s the kind of soul to always be on an adventure, but if you’re not his spiritual level you better back off cus he’s not taking 2 f**ks. He’s the kind of soul to have a license plate frame to say, “Move out the way, Id rather be barking at the cat next door.” He loves to eat treats but rather have yours. He’s one to live for baths but if he doesn’t get one… don’t worry about it because he already knows he’s having a good hair day.

Get the Middymug. A bum, typically a blonde chav who scrounges for change around Preston and makes no cash. Middy thinks he can cash but really he can’t, he cats off cherry drops and wears dead Burberry.
