Giving someone a gift but expecting it back when there is a falling out or if the gift is missed too much; the term originated with early European dealings with Native Americans when trade items were misinterpreted as gifts.
An old indian once gave me a scalp that he claimed had been in his family for 140 years and was taken off one of Custer's soldiers at the Battle of Little Big Horn, but the fucking Parire Nigger was an indian giver and demanded that I give it back after an antique dealer told him it was probably worth a couple of thousand dollars.
Well the term "indian giver" means you give something to someone, or do something, then you take it back, or demand for the same. So, butt sucking indian giver means.... well, use your imagination
