wagwan
A laid-back way of saying 'what's up?' or 'what's going on?'. It comes from Jamaican Patois and you'll hear it all over London.
Wagwan, fam? Haven't seen you in time.

allow it
Means 'stop that', 'leave it' or 'forget about it'. People often cut it down to just 'low it'.
Allow it, man, I'm not lending you money again.
bruv
Short for 'brother', but you say it to any mate or bloke, related or not. A bit like calling someone 'mate'.
Bruv, you're not gonna believe what just happened.
mandem
Your group of mates, usually the lads you roll with. Basically your crew.
I'm linking the mandem later to watch the match.
peak
When something's peak, it's bad luck or just plain awful, like 'that's rough'. Confusingly, in some parts of the UK people use it to mean the opposite, that something's good.
I missed the last bus home and my phone died, that's peak.
bare
Means loads of, or a lot of something. It also works like 'really' or 'very' to crank up whatever you're saying.
There were bare people at the party last night, it was bare jokes.
peng
Used when someone is really fit or good-looking. You can also say it about anything that's really good, and about food it means it's proper tasty.
Have you seen the new girl in our maths class? She's actually peng.
