easy crewsly, theres this guy at uni that always says 'wa blo' whenever i see him, i thought it might be part of the london gibberish lingo that i hear a lot of at the moment, but i cant figure it out. wha gwan people? (haha)
i believe that wha blow, has pretty much the same meaning as wha gwan. ruffly translated wha gwan, means 'what is going on', i.e how r u, wot r u up2 etc etc.
this is my guess at what wa blo means....
its a more hardcore version, evolved and far more advanced than a simple 'wha gwan'. i think the translation is simply 'whats blowin up' which is also 'hello sir, good day, how r u, what r u doin, how have u been'
it is nothing but slang, not much to be concerned about, just merely reply in future with
' not much man, bit tired, cant stop, gotta go, laters me bredrin'
hopefully the finishing statement will put their mind at ease and make them feel they r not the only one about talking the lingo.
