Get the Harrison mug.
The type of guy that always wants attention and will go to extreme lengths to get it. Some people see him as romantic and a funny sort of guy but many do not. He tends the not have the best of luck with girls and it means he ends up swooping low and trying to get with them way under his age. He can have mixed emotions and opinions about people and doesn't really talk to many people, which means the the friends he has tend to be close to him. That is what a Harrison is like!
"Hey, have you seen that attention seeking guy over there?" "He is so a Harrison!"

Verb
A Harrison is the act of receiving fellatio while sitting on a sofa drinking a beer and smoking an optional joint.
Q: "Are you coming out with the lads tonight?"
A: "I don't think so, mate. I'm just gonna stay in and get myself a Harrison."

"I had myself a quality Harrison last night!"

"So the missus dropped to her knees and pulled out my plonker, but I was like "Oi, cunt! Get me a beer first and meet me at the sofa so I can get myself a proper Harrison, like I deserve."

"Man, I had a great night last night."
"Really? What happened?"
"I was sitting on the sofa drinking a beer and my ho just comes along, whips out the one-eyed trouser snake, and starts chomping away!"
"Oh, you got yourself a Harrison!"
"Did I?"
"Yes"

"Buddy, if you engage in competition X, where you will have at least a 99% chance of winning, I will give you $5,000."
"What the fuck do I want $5,000 for? I just want to sit on the sofa, drink a beer, and get a blowie."
"I think you have problem. You are addicted to getting Harrison's."
"I know! I know! I know! I need help."

"The wife had to be taken into hospital."
"Oh dear. Why?"
"I knocked out all her teeth and broke her jaw."
"Fuck me."
"I know. Well, she has been giving me 3 Harrison's a day for 2 years, so I guess it's not surprising."
