I Don't Know, Man, It's Just Like...I Don't Know, Ya Know?
You use this when you're too dumb to understand the question and too lazy to figure it out. It's like your brain is on vacation and you're just there for the snacks.
'Why did you forget my birthday?' 'I don't know, man, it's just like... I don't know, ya know?'</p>
'Why did you lock me out?' 'I don't know, man, it's just like... I don't know, ya know?'</p>
'Why did you eat the last pizza?' 'I don't know, man, it's just like... I don't know, ya know?'</p>
