I have heard a few Hongkongers saying seven in a similar, likely identical, context. I assume they are addressing a person because when they say it, they make the L hand gesture. I could be wrong, but my intuition is that seven is a slang in Cantonese and means something like loser.
Did I guess it right? If not, what is the slang meaning of seven in Cantonese? Or is it just a random joke?
Thanks in advance!
