look up any word, like cunt:
a fun phrase used when a friend is sneezing/coughing up a storm or is just in a general state of mild sickness.

although it may be used in place of "I hope you feel better" or "I'm sorry you're sick", it functions more properly as "get better soon because your sickness is grossing me out"
Friend A: *sneezes 10 times in a row*
Friend B: "Don't die."
Friend A: "I'll do my best."
Friend B: "Good. I don't want your death on my hands. I'm too lazy to take you to the hospital."
