Sniggy Pig 

A Sniggy Pig is one who means a lot to another. It is almost exclusively used in an affectionate context but can be incorporated into everyday language also. Similar to other terms of affection, it is assumed one will only have one 'Sniggy Pig' at a time.

'Who is the girl you're with in that photo?'
'That's my Sniggy Pig'

shiggy 

Off-road hashing (running) trail through muck, mud or other wet areas. Term derives from shigella/shigellosis - bacteria causing dysentery occurring most frequently in areas of poor sanitation such as pig sties and back-water swamp lands. Term first used by Brits & Aussies on Hash House Harrier runs (in Asia) in 1940's.

The hares laid much of the trail through deep shiggy and nearly every hasher had to wash up prior to down-downs. On On!

Shiggy 

This is a slang, vague pronunciation of the acronym ISHYGDDT, like Humvee is a pronunciation of HMMWV. This originates from image boards like 4chan, particularly used after using the quote feature “>”.

>not knowing what ISHYGDDT means
shiggy

Which, without memeish language, translates to:
You’re implying you don’t know what “ISHYGDDT” means.

I seriously hope you guys don’t do this.
