This behaviour appears to be localised to South East, England (United Kingdom), however in neighbouring areas it is slowly spreading and growing popularity among social groups. The slow trend is attributed to the secretive nature and often only spoken about between close friends or pea-cocking barroom drunks.
'Troughing' is the commonly used term to encapsulate the different variants and branches of this act, and due to these variants and whispered conversations it is difficult to pin-point and remove all ambiguity. Due to trending via word of mouth between social groups 'Troughing' is believed to be evolving, improving and in some ways competing with previous variants for bragging rights.
It is believed that nearly all variants require food to be eaten, however the choice of food to be eaten (fruit, porridge, chocolate), by which partner (male, female), from where (boobs, belly, bowl, plate, floor, bed, bum crack, vagina, gooch), under which restrictions (tied up, no hands, hands only, spoon, straw, animal noises), with a variety of props (bowls, spoons, bib and not forgetting the TROUGH) and which location (bedroom, car, woods, picnic) is what provides all the variants.
