SAEDNEWS: “Shrek” is a slang term for a major downgrade and romantic downfall. It describes what happens when, after breaking up with your previous partner, you lower your standards too much and start dating someone who seems to be on a much lower level—only for that person to hurt you too and leave you completely wrecked.
According to Saednews, “You got Shrek’d” is a slang expression used when someone lowers their standards significantly after breaking up with a previous partner, starts dating someone they consider far below their previous partner, and then ends up getting cheated on or badly hurt by that person too.
You got Shrek’d means downgrading and getting badly burned in the process.
The phrase describes a situation where, after breaking up with an ex, someone lowers their standards and gets into a relationship with a person they see as being on a much lower level. However, that person still treats them badly, cheats on them, or ultimately destroys the relationship.

The expression is usually used jokingly or sarcastically to describe someone who made what they thought was a downgrade from their previous relationship, only to have that new relationship end even worse.
“After dating that model-looking guy, he got into a relationship with this dude and ended up getting cheated on. He really got Shrek’d.”
Hard is another slang term that can mean intense, rough, or severe. It can be used when something—such as a workout, situation, or someone's tone—is particularly difficult or intense.
