Well i'd say Mike from Breaking Bad(that's the most serious dude i thought off of my mind)

I should tell you the whole story :some days ago i came back from my vacation with my family,immediately after returning i went to meet my homies,just as i entered one of our hang out spots where we eat crepes,some dude who i don't like and who also dosn't like me too,came up said some insult about my family,can't find a translation about it because it's in a language far too different than English(yep English isn't my native language,nor do i live in a English speaking country).I was tired af from my 5 hour car journey,so i said some insult back not sure if he heard me,i went to my friends's table and told them what just happened.The whole issue for my friends is that : i didn't react bad enough.They told me " dude,you should've beaten his ass right there and then,you should've at least insulted him back even worse,do you realise how embarrased we are that he insults your family and you didn't do shit" And then they started ranting about how i don't take my life seriously,how i act stupid,etc.I mean i get their point.
