The genius that is Mike Shinoda of Linkin Park and Fort Minor.

For the reason why, Mike said to ask Celph Titled (since he's the one saying it in all the songs).
Fort Minor - S.C.O.M
"Shinoda the Cobra Holder, you a fool for this beat"

Fort Minor - Respect 4 Grandma
"This is M Shinoda, the cobra holder..."

Fort Minor - Cover and Duck
"We had to get real Godzilla on 'em this time
Talkin' Ryu, S.O.B., Celph Titled
M. Shinoda the Cobra Holder, Demigodz
That's how my crew do, shut the fuck up when Fort Minor's talking!"

The guy/girl that is dated or messed around with until the user can get the guy/girl that ditched them to come back.

Often the user was just a place-holder for said ex and didn't know it/can't get over him/her.
girl:Oh yeah I can't wait to hang out with you tomorrow <33!! love you baby
guy:*awesome this is love ^.^*

The following Evening:

girl:Yeah...I'm back with <insert douchebag that just ruined your fucking life> and I wasn't really in love with you.
guy:*Holy fucking shit I'm going to kill myself as soon as I finish thinking this.*

Perfect example of a Place-Holder...often suicide IS the result of being a Place-holder.
Other results are binge-drinking and death threats.

Bra - A word originating from the West Midlands and North of England. Bap tends to mean breast in the north, therefore, a bap holder holds baps. A bra!
"Annie, are you wearing your bap holder in bed tonight?"

"No, Eric. I have left my bap holder off tonight so you can cup my baps while we spoon"

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
