NOTE: Street Dancers are not b-boys. Street dancing is stupid POP like dance with a street name to make it more appealing to the YOUTHS AND URBANS. Movies like you got served are absolutely fake although it does have some elements of Breakdancing, in the real world it would be b-boying not things you see Backstreet boys do.
Do you want to breakdance ? They are most likely not to much into hiphop itself and do not study its backgrounds lifestyle etc. DOESNT MEAN he is bad at b-boying. It could also be he just started and doesnt know the slang yet.
You wana go B-boying ? Someone that has been studying the 4 elements of hiphop and has most likely got a b-boy name for example B-boy Flash, B-boy Flex or B-boy Blaze.
