Fucking Bastard Wank Piece of Shit
AAaaahh... The genteel call of the Greater Miffed Squaddie.
If you happen to be passing the habitat or nesting ground of the species, you may be fortunate enough to hear dulcet tones berating the latest specimen of dysfunctional equipment spawned from the Procurement Decisions of the inept and feckless Civil Servants in charge of British Military Procurement Mysteries.
The call can also denote extreme displeasure at any item/thing/person/place that is (or is performing to) less than the expected standard.
Could also be applied to any of the products of Microshite that fine purveyor of computer software.
