FABFAST:- Is the description of something, like the MIG69, flashing overhead SO fast that it might only have been heard many minutes later.
We've just godda get a couple of FABARMS to fix this out FABFAST, some people say they make a MIG69 look slower than a dogturd, languishing on the pavement for months whilst it's slowly spread around the pavements by "UNTERSHOE".
