The chemistry related jargon for a triple bond, most commonly a carbon to carbon triple bond.

Macho bonds are characterised by their extreme strength, curled moustaches and ability to kick ass against almost any other chemistry related jargon.
E.g.
SciGuy: C=C has a pretty high boiling point but C≡C would kick it's ass any day, it's so Macho.
Class Orgasm: Macho Bond !!!
