When a person failure is so far beyond the limitations of the word fail.
Person A: I just met a guy at a bar who told me he loved me, I was so happy that I slept with him.
Person B: Really? You have Failed^2 in life.
Normally referred to a single individual, however, it can be directed to a group as well. It is often used when someone or a group of people are epically struggling at something and/or losing.
"Wow, the green team is getting owned by the yellow team."
"I guess it's time to brew a cup of fail for the Green Team".
When two or more fails happen at the same to a single person.
Self explanatory. Compound fail.
To "safety fail" is to intentionally fail or fail to complete a major assignment or test in a given class because (according to calculations) it is impossible for the assignment to cause one's overall grade in the class to drop by a letter or have any significant changes
Sarah: Hey what are did you write about on the essay for the final in English?
Chris: Haha I didn't...I took a nap. I had over a 100% in that class so it wouldn't have changed my grade. I might as well have safety failed it.
When a cheap person regifts something and the reciever unwraps it to discover it is blatantly secondhand.
My friend regifted my DD an Easter egg sticky-taped to a dirty coffee mug, which had coffee residue and spoon marks in the base of the mug. Regift fail.
When Royal Mail just can't get it right and struggle to deliver your parcels on time. Sometimes they will deliver your items early such as the very next day after you post it whilst at other times they can take twice as long as the estimated delivery time and you get worried about where the parcel is. They are kind of like a rollercoaster between good and bad in a way.
Person 1: When will my parcel arrive.
Person 2: Whenever Royal Mail delivers it.
Person 1: I've waited a week.
Person 2: I know Royal Fail can be like that sometimes.
What a stupid idiot says on Facebook posts to get attention.
