Someone doesn't know a curse from a coincidence from a correlation from a cause and effect.
Curse, is bad luck not limited to any one activity. If all the injuries to guys who had #37 were in odd places such as slipping while getting off the team bus and pulling a groin, a sprained wrist getting a girlfriend's bra hasp undone, or chocking at the pre-game buffet on a hard-boiled egg, you might have a curse. A correlation is observing that when one strident famous poster on the site gets banned, another comes to life and then disappears when that poster's ban is lifted, but reappears when that poster checks out on sabbatical. A coincidence is a short term repeated sequence of random events, like BJ's from the fiancee 3 night in a row, (absent a recent offing of a diamond ring) A cause and effect is raising an eyebrow amazing at the inanity of every single post of a single poster (or BJ's 3 nights in a row after giving a fiancee a diamond ring)
That clarified, back to the claim of a 37 curse. Curse is just a coincidence for dummies.
