First Light 

When a telescope or astronomical instrument is first used to take an image after construction.

I just started to build a 100 meter optical telescope in my backyard: first light will be in 2038.

First Light 

The first lighting of the sky after night and before dawn when the stars begin to dim. Surfers first check the waves at this time.

Hey dude, I'll meet you at Cardiff at first light to shred the gnar-gnar.

love at first light 

Waking up in bed with someone, not remembering the night before, but instantly falling in love with them as soon as you open your eyes.

Johnny didn't remember how he got there, but when he woke up in the morning next to Mary he knew that was where he wanted to wake up the rest of his life - it was love at first light.

Cheeks 

An Irish phrase meaning shit, derived from ass
(Not to be confused with the literal description of one's buttocks)

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."

Breadhead 

Someone who is addicted to obtaining money and building wealth. A money addict and fanatic. Breadheads often work more than one full-time job, and some even participate in illicit activities to "obtain the bread".

A breadhead is like a crackhead, but for money instead of crack.
