Term first found in the lyrics for SR-71s song 'Right Now'. Nobody really knows what it means, but Todd in the Shadows estimated it might stand for a fake, slutty girlfriend.

Sarah: My mom is always watching over me. She is totally a helicopter mom!
Caitlynn: My mom pops in once a year to ask how I’m doing and borrow a few dollars. She’s totally a submarine mom!

One of the few songs by The Beatles where Ringo Starr is the lead singer. Also one of their greatest songs ever.
(Ringo)
In the town where I was born
Lived a man who sailed the sea
And he told us of his life
In the land of submarines
So we sailed into the sun
'Til we found the sea of green
And we lived beneath the waves
In our yellow submarine
(All)
We all live in a yellow submarine
A yellow submarine, yellow submarine
We all live in a yellow submarine
A yellow submarine, yellow submarine
In the town where I was born
Lived a man who sailed the sea
And he told us of his life
In the land of submarines
So we sailed into the sun
'Til we found the sea of green
And we lived beneath the waves
In our yellow submarine
(All)
We all live in a yellow submarine
A yellow submarine, yellow submarine
We all live in a yellow submarine
A yellow submarine, yellow submarine

A Muslim who converts to or practices Islam without revealing their conversion or Islamic faith. They practice Islam in secret - sometimes not even telling their own family members. Reasons for this behaviour includes not wanting to be discriminated against; avoiding the drama associated with Islam's stance on homosexuality / Palestine etc; avoiding fallout issues with family members and friends.
