Funny enough, I found that this was a 19th century Austrian tradition, where couples in courtship would keep a slice of apple crammed under their armpit during dances, and at the end of the evening, the girl would give the guy she most fancied her used fruit, and if the feeling was mutual, he would wolf down that stinky apple.
Zanimljivo, otkrila sam da je ovo bila tradicija u Austriji u 19. stoljeću, kada su parovi kao dio udvaranja držali komadić jabuke ispod pazuha tijekom plesa, a na kraju večeri, djevojka bi dala taj komadić mladiću koji joj se najviše svidio i ako je osjećaj bio obostran, on bi pojeo tu smrdjivu jabuku.
