Drunken, bikini-clad Cambridge University students were seen collapsing and throwing up after binge drinking at midday on a Sunday afternoon.
The students were spotted struggling to stand up after a wild end-of-exams party, tagged Suicide Sunday.
The bash was allegedly organised by Wyverns, an all-male Magdalene College drinking society, at a new location after students were banned from carrying out the event on university premises.
"It was only midday on Sunday and there were lots of families and young people around enjoying the sunshine," The Sun quoted one outraged passer-by as saying.
"The students were lying across the verges, lots of them were vomiting and they were singing rowdy drinking songs," the passer-by added.
The females were seen fighting it out during the jelly wrestling contest, during which they threw jelly at each other in a pool, to bag the 250-pound prize.
One student said: "It was a very hot day and some students drank far too much. The event involves lots of drinking games and you soon lose track of how much you've drunk. A lot of people could hardly walk by the end of it."
The students also underwent taxing initiations between the parties, which included guzzling alcohol-free drinks through a fish smeared in marmite and licking cream off a half-naked stranger.
