All right a little HC talk. While this would be my most favoured line in punk if I had to choose, I know very little on Hungarian bands for two reasons: 1. the lyrics either English, then the vocalist accent ruins everything for me; 2. or Hungarian, then it's simply the vocalist's voice that makes me cringe. The already listed punk bands' - liek CPg or Aurora - vocalists have bad voice and what will come in later posts will continue this line but I can get used to it, and it kinda fits the genre. But HC should be hard, with hard vocals and I just can't accept that halfway stuck in puberty voice. For this reason I just can't listen Agnostic Front no matter how the pull off the music.
So what's left is basically Action. Maybe there are others that would suit me, they're just little more obscure probably. I also have a pal to ask, he knows this stuff very well, but I couldn't recommend a band which I just got to know.
Action originally was Sex Action and played "dirty rock", with "sex, drugs, rock n roll" lyrics but with heavy emphasis on sex. Then in the middle of the '90s, they changed image and music and moved to hardcore punk and recorded a few albums, two I listened extensively and two partially. Lyrics got more violent, with nice graphic descriptions, they were about life on the streets, the "drugs" theme turned to negative, it's the cause of the people's suffering. On later albums they softened lot and brought in other styles. Again sexual themes moved to front, and finally they disbanded Action to recreate Sex Action.

A következő a sorban (The Next in the Line) my translation won't be good, I'm not familiar with junkie lingo.

You have the needle
Ready to shoot
While people starve to death
Just snorting the lines
Until they find your corpse
Your body can't handle your mind
As you got spun by the substance
And you end in the machine
As you saw it in a picture

All your money is blown on the snow
