Hi Nikita! Superman is using the slang meaning of 'roll' to make a joke about her Sushi invitation. 'You know how I roll' is basically the same as saying 'You know me. You know what I like / what I like to do / What I can do.' Sushi is made by rolling raw fish and other various ingredients in rice and seaweed. So, Superman is not only confirming that he will be joining Lois for the sushi, but also creating a pun out of the situation and making a pretty clever joke. I hope this helps !

You're most welcome! =)

Thank you, Charles and Jingle!

I don't know where this very colloquial expression originated from, but the way you 'roll' is the way you do things, your style of living, your habits, the way you move or the moves you make. It's a stupid expression and it's almost always made in a joking sense. In the above dialogue it's a play-on-words because sushi restaurants in the US mostly serve 'sushi rolls'/makizushi. So he means that he loves sushi rolls and he made a pun about the expression about how people 'roll'.

Hi Nikita! Haha yes, he was trying to joke around haha.. So, actually the sentence "You know how i roll" or "That's how i roll" means "This is the way i am." or "This is the way i work." But he made it like a joke because he's referring to the sushi, XD cause when you make sushi you need to "roll" them haha So he confirmed that they will make the sushi but in a funny way =D That's my interpretation, hope it helps! haha
