look up any word, like donkey punch:
Do have dubious facial qualities. To be ugly.
"You see that Pink? She's got a face like a melted welly"

Taken from 'Rogers Profanisaurus'

A poetic term describing a lady's bodily treasure.
'Spatula was powerless to resist. His eyes burnt into hers like mamellated chalcedony. His muscular arms enfolded her body as she felt herself being swept away on a noctilucent cloud of passion. "Am I the first?" whispered Dartanyan. "Sort of," she vouchsafed in return, her voice quivering with unrequited passion. "I've not let the other two have a shot on me melted welly yet."'
