hummahummafricfrac 

Something to say in place of "so on and so forth" or "yada yada yada" or "the whole 9 yards." Useful when you want to cut to the chase.

"So, SGT Snuffy told PVT Parts to go clean the latrine, hummahummafricfrac, and leaves Parts to his own devices. Sure enough, SGT Snuffy came by an hour later and Parts was still standing outside the orderly room, smoking cigarettes. Needless to say, Snuffy's PISSED, threatening Parts with an Article 15, reduction in rank, hummahummafricfrac."
