emailing under the influence; modern variant on drunk-dialing
Did you really google that girl you had a crush on at summer camp and email her asking her to move in with you?

Yeah, total E.U.I. She's going to be here on Thursday in a Uhaul.

EUI
Making large unrealistic bids for items on auction sites like (EBAY) . Usually after excess drinking or drugging . Buyers remorse follows after checking email the next morning & finding bid confirmations for unwanted items .
I bid up that Beemer on (EBAY) then found out the next AM that I won it & cost is three grand to ship
worst EUI ever
