Quite simply, a 'greasy mullet'. This is the state hair gets in when you don't wash it for a couple of days, stand in smoky pubs, eat a few too many kebabs and finally dip your head in a last nights chip fat. A Gomper will often be found with hair such as this.
Once again, after a few nights worth of burning the candle at both ends, James's hair resembled a grullet.

Someone who walks awkwardly, almost as if they were wearing an invisible deep sea diving suit. Similar to the 'lollop' that an elephant adopts when walking. A 'gomper' is also normally half a sleep while all those around them are awake.
