snotfest 

A collective term for when a group of people (e.g. family, work colleagues) who are co-located suffer from a bad cold that results in copious sneezing and excessive nasal mucus.

Basically, a festival of snot.

We were supposed to go to Alton Towers at the weekend but the family had a snotfest so we had to cancel.

Snogfestation 

When multiple couples in an area start snogging at the same time, as if it's contagious. Used derogatorily by single people or those who dislike public signs of affection.

A disgusting snogfestation broke out at the party last night.

His rendition of 'Lady in Red' caused a bad case of snogfestion to set in.
