it's either of three (if only):
1. stupid (thing) - when someone finds somethingdifficult to comprehend;
2. stupid (person) - same as above;
3. stupid (situation) - as before but see below.
- I can't understand how people can live in temperatures below zero. It's just stupid! For me 'zero' is too cold!
- I think it's just you who's stupid here if you can't understand that!
- No! This whole conversation is just stupid! (meaning how could it be that it's 'just' me?)
1)"I only got 4% in the maths test, I'm so stupid"
2)"Amy was running up and down in a chicken costme, she's stupid"
3)"Bob brought drugs to school"
"That was stupid"
4)I do not mind people having their own opinions, but this site is stupid. People come on this site just to insult others an others' opinions which just pisses other people off. This was an Ok idea fora website, but the people who insist on insutlting others have jst ruined it.
