I heard a sentence - Springfield you sucks from the American cartoon - The Simpsons. I often heard the word - sucks in some people's dialogue, but I don't really understand what it means. Here're two entries I excerpted from my dictionary. I think they might be close to the context.
# 1 Vulgar Slang To perform fellatio on.
# 2 Vulgar Slang To be disgustingly disagreeable or offensive.
Does 'suck' mean quite disagreeable here? If something sucks, does it mean something peforms fellation so that is disgusting?
Btw, why is the verb -suck in singular sucks but not 'suck' since it is after 'you'?
Thanks!
