To place the tips of the fingers against one's own forehead, as if trying to access something
recalcitrant from the brain.
(Derived from "
mind meld," coined by the original television series Star Trek, referring to a technique employed by Mr.
Spock to access the thoughts and emotions of another being.)
From a prose adaptation of
David Mamet's Glengarry Glen Ross:
"...how are you?" Ricky asked, finally noticing George's agitation.
"Fine.... You mean the board? How am I doing on the board?"
"Okay," Ricky said, slightly bewildered. "The board."
"I'm fucked on the board! My mind must be other places," George said, performing a
mine meld, "Because I can't... I can't..."
"You can't do what?" Ricky barked impatiently.
