To wank over a mangy flange! Wanking over a fetid minge. when you just can't get that one munters manky bits from yer mind so you just carry on.
1) "That birds minge was so minging I flangewanked, coz I wouldn't/couldn't stick it in THAT!"
2) "Had a flangewank, just couldn't get the image of that bird eating a beer can in her furry cup out of my head!"
