Shagsie is the ultimate compliment, to be called shagsie you have to be a top shagsie, you have to love being derogatory towards women and sniffing lots of packet.

The word shagsie originated in Brixton from a proper top shagsie called Tom Milne, the man is a national treasure and therefore is the king of all shagsies.

Using the word shagsie after a phrase is a very good way of having shagsie related banter with the lads. For example fuckin hell Shagsie Malone you are a hero.
Tom Milne: SHAGSIE!
Drakey Hall: What's happening Double O Shagsie, shaken then shagsied?
Scott Pickles: Yes Shagsie's! We gonna go chase some minky tonight and try get our lengths away like the shagsies we are?
Tom Milne & Drakey Hall: Of course we are fuckin SHAGSIE!!!
