He was joking at first, but then he crossed the line and made everyone uncomfortable.
In my opinion, it's important to speak honestly, but if you insult someone, you cross the line and it becomes disrespectful.
Fix the pattern
One small grammar move makes it sound right.
Not: She crossed over the line with that remark.
Say: She crossed the line with that remark.
The fixed idiom is 'cross the line' — not 'cross over the line'.
Which sounds natural?
Tap the one a native speaker would say.
'Crossed the line' says 'went too far' in three words; the formal version reads like a disciplinary letter.
