"I'm off to my gal's place for a lil' i and i."
Used in the rastafarian religion in place of "you and me" to show that all people are equal under Jah.
Your parents are coming to see I and I.
Also means "I, with God's help" or "I, with God-in-me". Often used in place of "me". Because the people's Identity was destroyed in slavery, Identity is very important in RastafarI -- so I gets capitalIzed a lot. They pronounce the I's strongly in reggae songs. Emperor Haile Selassie I is not "the First" but "Haile Selassie *I*."
I and I build the cabin
I and I plant the corn
Didn't my people before me
slave for this country?
Jah Bob Marley
Previous definitions are good, but miss out on one thing.
the "I and I" also marks a distinktion between the body (that which can be seen) and the spirit. This is reinforced by the similarity of sound between "I and I" and "eye and I".
The expression "I and I" thus expressedly includes all of ones being.
Also it can be used straight of as a possessive pronoun.
"I an I don like it!";
"Is tha fe I an I?";
"It belongs to I and I".
