A Holder Handshake is a ritual carried out by homosexuals.
It involves holding onto a males long curly 70's styled hair while inserting a clenched fist into their anus.
A holder handshake was named after the 1970's icon Noddy Holder (because of the hairstyle... Not the act in question)
Example:
Steve - So you went down to the gay village last night. Did you pull?
Drew - Yeah. I received a massive holder handshake
Steve - hahaha. I thought you were limping
