Wumbling: the action of grabbing or gently gripping another's
cheeks, stomach or bottom, before gently vibrating it from side to side with either your hands or, in exceptional conditions, your
mouth. Colloquial derivative from the
English, 'to womble'.
'
Y' lay quietly and peacefully on the
bed. Her boyfriend, 'T', blustered stridently through the door before climbing on
top of her, pulling up her cotton jumper, before wumbling her belly.
'Crikey
Jack, Ieuan's wumbling the neighbours dog again!'
Or from the song:
'Wumble on. Wumble oon. Without, the need to fart, for you'll never wumble alone - you'll neever wumble, alone'. (circa 1954).
