Sicknote 

Nickname for someone who is continually off work "sick", usually faking it because they are simply too lazy or irresponsible and can't be bothered to come in to work like the rest of us. Most of the time they don't even bother to call in with a reason.

"Where's 'sicknote' today?"
"Off work .... again"

Ultra Instinct Sicko Mode 

Ultra Instinct Sicko Mode is the highest level of sicko mode that can currently be achieved. It is where a person ascends to the highest level of existence. This results in the sudden absolute peak of physical and intellectual prowess where a person can act purely on instinct. As such, this mode is another way of saying that they are immortal.

"Holy fucking shit!! Daniel... he's going Ultra Instinct Sicko Mode! There's no way we can possibly defeat him now!!"
