Heating Up/On Fire

A rule in beer pong which states that if a player makes three cups in a row without missing, he/she may continue shooting on his/her turn until he/she misses. Although house rules vary, the player may have to call when he/she is heating up. Upon successfully making two cups, the player would have to call "Heating up," and after the third consecutive cup, the player would have to call, "On fire."
"Are we playing the heating up/on fire rule?"

hetbaiting 

When a closeted celebrity is put into stunts, headlines, relationships/bearding in order to appear heterosexual.

‘Hetbaiting’ is selling a majority straight fanbase the unattainable but possible fantasy of being with this celebrity.
“No, they’re not straight. They were told their career would be over if they were queer, so they had to hetbait for years before they came out.”

“Maybe he isn’t queerbaiting and instead queerflagging? I think he may be forced to participate in hetbaiting due to his fanbase. That makes more sense.”

“She happily came out as a lesbian after years of being confirmed to be bisexual and only seen with men. Hetbaiting at its finest.”

“Real people can’t queerbait. But there is lots of money to be made from heterosexuality. Their PR team hetbaited this celebrity for years while they got accused of queerbaiting. How sad.”

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
