What Japanese scientists do on their break.

Lab coats must be cheap.

Engineering frat parties are a decidedly different affair, no crude beer pong here folks. But we still abuse the pledges.

uhhhh

While there is certainly a pretty awful trend of laughing at male rape, particularly in prison scenarios ("don't drop the soap" etc), this isn't really it.

The "victim" here is presumably there by his own choice.

Well, I guess we can flip it around then and see if it's still funny.

Imagine the same situation with a skinny young adult woman sitting there with her legs spread open. Nervously laughing and obviously doesn't want to be violated by the screwlike device. But she stays there because this is her job and allows the activity to complete until it is too painful and she jumps up and runs away while everyone is laughing.

Hmm.. not funny, even if they are being paid for it. Financial coercion to do these types of degrading acts isn't right but it's probably legal. So I guess you can legally laugh.

Look, this is basically Japanese "jackass". It's a bunch of idiots hurting themselves for our (and their) amusement. The gender doesn't matter.

He didn't get nailed, he got screwed.

Big difference.
