H as F - It’s when you’re so bored you start typing random letters on

It’s when you’re so bored you start typing random letters on your keyboard just to waste time.

I was so bored I typed H as F on my keyboard and then laughed like a maniac.

I was in class and started typing H as F and my teacher looked at me like I was crazy.

I was watching TV and typed H as F just because I was so bored.
