During the covid epidemic in Australia politicians made many decisions "Based on Health Advice". At the start these were legitimate however over time they were politicised and used to further politicians agendas. Particularly in the Hermit Kingdom of Westralia where this was recognised amongst the doona dwellers and the term BHA quickly became a satirical phrase to excuse bad behaviour.
"BHA (Based on Health Advice) it's your shout".

"I told my missus, BHA (Based on Health Advice) you're on top tonight"
"BHA (Based on Health Advice) you're on dunny duty again"
"Sorry dude, BHA (Based on Health Advice) you're not invited"

The cognitive process by which an individual makes a decision based solely on the emotional gratification he or she received while viewing that decision played out in a montage movie style format. In this montage, the individual is the main character of a super epic story, in which they are better looking than they actually are. However, this montage has no connection whatsoever to reality and the end result is disastrous consequences, wasted time, and usually suicide before the age of 35.
Mick: Dude, I'm thinking of studying cinematography out West, I think I could be really good at it and I see myself in my head just killing it all the time and being dope.

Jack: dude, don't do that. That's Montage Based Decision Making (MBDM).
Mick: ye.

fourth-base shortcut

Refers to the act of bypassing second and third base, but instead proceeding directly from first to fourth base; i.e., having sex with a girl right away, without bothering to tediously wade through the whole hugging/kissing/touchy-feely foreplay-crap in between.
The simplest and most effective/successful fourth-base shortcut procedure, in two easy steps:
(1) Find a hot chick and offer her a free foot-massage (first base).
(2) When the cutie obligingly plops herself down and gives you her feet, take one foot in each hand and start rubbing them, but also gradually raise them up high till her legs are back over her head and her butt is lifted off the ground, allowing you to slip off whatever lower garment(s) she's wearing. If she'd made no objections by that time, then the rest is easy; just kick off your own lower garments and enjoy (fourth base).
