This is the hall of shame: the lines readers voted to the bottom, preserved because terrible has its own uses. Delivered knowingly, a famously awful line becomes a joke about pick up lines — the listener laughs at the genre, and you get credit for the meta-move without risking sincerity.
Read a few aloud with friends and you'll find the other use: nothing bonds a group faster than competitive appreciation of the truly dire.
A bottom-rated line is a finished joke with the punchline pre-installed: "someone actually wrote this" is the shared laugh, and delivering one ironically is the lowest-risk opener on the site — the line takes the fall, you take the credit. Bad-pick-up-line contests among friends are this category's true habitat, and it is undefeated there.
For material that fails upward differently, the awkward and sad collections weaponise other flavours of defeat, while the cheesy lines show how bad-on-purpose is done with polish.
