Looking for a modern-rock song

Question

There's a song I heard at the mall once that sort of reminded me of something similar to "Green day" here's what I remember,

• The song's chorus repeated something like "You don't wanna, you don't wanna know"
• The vocalist was a male
• The song sounded as if it was in either the 2000s or late 90s

Answer 1

With your description, this looks like "Baby You Don't Wanna Know" by Sum 41.
