Two homosexual blokes giving pleasure (and and pain) in doing an activity of cock-in-cock.
Using kitchen tools to help spread one bellend apart while the second male penetrates fiercely while screaming 'bellpen time', giving both pain and pleasure.
Tip of the penis.
Can also be used as an insult.
Only Britain has been blessed with this amazing word so far, but the Gods are trying to find a way to spread it around the entire world.
Random: I dress up as death and point at old people as they leave the bingo centre.
Me: You bellend.
Holding cells were called "bullpens" because police officers were at the time called bulls. Bullpens are still the name inmates call holding cells. You are held in the bullpen at county jail until the bus takes you to court. At court you are held in another bullpen until you are called in front of the judge. Then you are escorted back to the bullpen and are held there until all the inmates are called in front of the judge. Then everyone is escorted back to the bus and sent back to county jail where you sit in another bullpen until you are escorted back to your housing unit.
Damn I sat in the bullpen for 8 hours today before I was called in front of the judge!
This type of person is an absolute twat who never fails to annoy you. They are loud and not well educated and often blurt out inappropriate comments resembling an arsehole, or in this case, a total bellend.
That new lad at work is a boisterous bellend and really pisses me off
