Developed from commentary by Jeremy Clarkson on Top Gear:
1. A people-carrier/minivan, especially one that is being driven in a manner that is inconvenient to you.
2. The driver of a people-carrier/minivan, or a person who looks like he might drive one.
1. That piddington is going 12mph in a 50 and I can't see around its fat ass to tell whether or not I can pass it.
2. This place is clogged with piddingtons; must be a Michael Buble' concert in town tonight.
Nobody really knows what a Pidington is, it's just something you don't want to be.
I have a people carrier, I am a bit of a Piddington.
I like kippers, I am a bit of a piddington.
