Here's some:

Southern blotting: blotting of denatured DNA onto membrane, probe with
    DNA or RNA

Northern blotting: blotting of denatured RNA onto membrane, probe with
    RNA or DNA

Western blotting: blotting of denatured protein onto membrane, probe with

Southern Cross blotting: blotting of 1 wide lane of restricted DNA onto a
    filter, probe with another single-lane digest of end-labelled DNA from
    a gel turned at right-angles to the first (to detect common sequences
    between fragments in different digests)

Middle Eastern blotting: blotting of RNA onto membrane, using it as
    substrate for in vitro translation, detection of translation product
    using antibody

South-Western blotting: getting drunk on Hansa Pilsener [local joke:
    Namibia used to be called SOuth_west Africa, and they make very good
    beer there...!]
