They are dobbers aren't they!!
Not being a Northern lad never used that one before so I dived into the etymology.
1. Dobber , dobbing , dobbin' :- something 'big' - big headache, big penis, big idiot, big fool
1a. England:- A 'dobber' is a large marble (small glass coloured balls kids used to play with)
2. Australia, NZ (?):- to 'dob' someone in means to squeal on someone, to expose them, tell on them
I'll match my blue dobber against your medium stripey marble.
However this one might apply too..
A fat northen male or female who live off Greggs, always seen wearing tight leggings and Everlast Tee shirts. The whole family look the same, hence 'look at those fucking dobbers!'
fat dole scum, smokes rollups and waddle when they walk, they even have tits on there backs as there so fat, 'What a pair of dobbers'.
Now this one really got me going...
Dobbers, a powerful phychoactive drug, has many effects, which include, but are not limited to: Uncontrollable fits of laughter, general coordination loss; especially with balance, and increased appreciation of Starbucks, vision problems (may include walls not appearing, which can lead to collisions), and general giddiness. A Dobbers overdose can occur, and the symptons include laughter which reduces the victim to tears, and collapse onto the floor, writhing hysterically.
Yo man, this Dobbers shit is so good, im trippin balls right now bro!
