Give a hummingbird a heart attack 

Used to refer to the effect of an extremely large amount of stimulants generally taken during night-before-test study sessions, or when writing a 30+ page thesis due in several hours.

Guy: "Yes, I stayed up all night and had enough Red Bull to give a hummingbird a heart attack, but I finished my thesis two minutes before I had to present it"

text message heart attack 

Getting a text message while zoning out or in the middle of the night (while sleeping, preferably) that scares you out of your skin, gives you a quick adrenaline rush, then leaves you with a slightly worn down heart and a bad message from someone you don’t really care that much about.

I got a text message heart attack last night when you woke me up at 2am with your pointless message!
