In blind swine mate, a rook on the seventh rank delivers checkmate to the king on the back-rank. The rook is protected by another rook on the seventh rank.

Explanation

Two rooks on the seventh rank can be very powerful and wreak havoc.
Such a pair of rooks is sometimes called "the pigs" because they run around wildly and eat up everything in their path.

Two rooks on the seventh rank cannot force a checkmate, if the king has enough escape squares.
For example, in this position, the king has two escape squares. White cannot win, e.g.
1.Rg7+ Kh8 (not 1...Kf8? 2.Raf7#) 2.Rh7+ Kg8 3.Rag7# Kf8 4.Rf7+ Kg8 etc.

This is why the rooks on the 7th rank are sometimes called the "blind swines", as they are unable to find checkmate.

If the king does not have enough escape squares, a checkmate can be achieved:

White can give checkmate with 1.Rg7+ Kh8 2.Rh7+ Kg8 3.Rag7#.
This checkmate is then called the blind swine mate.
