faffalanche 

Portmanteau of the words faff and avalanche.

Generally used to describe a situation where one persons faffing causes a series of faffs from several people, usually resulting in delay.

These faffs would most likely have not occured were it not for the initial faffer, therefore they have caused a faffalanche.

Example 1: Group of people just about ready to leave the house.

Person 1: "Taxi's here!"
Person 2: "Oh, hang on, im going to change my shirt"
Person 3: "I might change mine if you are"
Person 4: "Im going to use the toilet while you do that"
Person 5: "Im going to grab another beer then"

A faffalanche has been caused.

Example 2:

Person 2: "I might change my shirt"
Person 1: "Don't, the taxi's here and you'll cause a faffalanche"

A faffalanche has been prevented.

Fatalanche 

Alt Def: When the flesh rolls of a morbidly obese individual land on you while sitting at a sporting event, public performance, or on a plane, bus, or train.

Ex. Jack almost got buried in a fatalanche when a giant fat kid sat next to him at the Tiger’s game.
