Delibbleate
To deliberate over something for an inordinate period of time resulting in the annoyance of companions and potential vendors of inexpensive high street fashion.
God I was in TopBloke the other day with Geoff McGrugin and he couldn't make his bloody mind up about a pair of trainers he wanted, he was just delibbleating for sixteen minutes about whether they made him look like Craig David or not, twat.
