What is Brightside?
1.
In a reference to the song "Mr. Brightside" by the Killers, a brightside is someone who is jealous of his/her ex's new beau.
"He takes off her dress now
Let me go
And I just can't look
It's killing me
And taking control"
"Destiny is calling me
Open up my eager eyes
I'm Mr. Brightside"
2.
Someone who pretends to be happy when they're not, referring to the confused bisexual narrator of The Killers' album Hot Fuss.
But it's just the price I pay
Destiny is calling me
Open up my eager eyes
'Cause I'm Mr Brightside
