A Full Ethiopian
A full Ethiopian is like the worst luck ever. You use it to mock someone who thinks they're super lucky.
Friend: 'I got a new car!' Me: 'Oh yeah, I saw a full Ethiopian trying to park next to me.'
Cousin: 'I just got married!' Me: 'Oh yeah, I saw a full Ethiopian at the wedding.'
Stranger: 'I just got a raise!' Me: 'Oh yeah, I saw a full Ethiopian in the office.'
