Bronsted-Lowry/Brønsted–Lowry Acid-Base Theory

An acid/base definition that suggests an Brønsted–Lowry acid is any molecule that can donate a proton, and a Brønsted–Lowry base is any molecule that accepts the proton. Protons can be referred to as H+ or "hydrogen ions," so if you see those terms used in a textbook they all mean the same thing. When a Brønsted–Lowry acid gives its proton away, it is "deprotonated" and can now accept a proton; now that it has become an acceptor, it is referred to as a conjugate base. The same rule applies to Brønsted–Lowry bases: once they gain a proton (are protonated), they are known as conjugate acids.

student: i'm a little confused with this functional group. the reading says that the carboxylic acid (COOH) group loses its proton, H, making the formula COO−. now that there's a space on the oxygen that's vacant, could the group accept a proton in the empty space? wouldn't that make the group a base?
teacher: yeah, acids turn into things known as conjugate bases when they lose hydrogen ions. the space where a proton used to be is now available for bonding, and the group or molecule becomes a proton acceptor/Brønsted–Lowry base
that's how you use the Bronsted-Lowry/Brønsted–Lowry Acid-Base Theory

Queer/Trans Sex Bases

1st Base: Everything from the introductions through to sex. An average of 4 hours elapses between meeting and f*cking.

2nd Base: Unprotected sex. Rough and intense, light kinks such as name-calling, spanking, and slapping. Partner ideally interacts with ejaculate.

(2nd Date - Lesbians stereotypically move and co-habitate with a partner at this point)

3rd Base: More intense and specified kinks. Examples include bondage, impact/flogging, degradation, discipline, watersports, blood play, choking, ect...

4th Base: Less Mainstream Kinks such as pup play/training, roleplay SA fantasy, master/owner dynamic, scat, ect...

4th base might be true love 😆

Queer/Trans Sex Bases : Simile Comparing the bases in baseball as an incremental development of physical intimate activities from kissing upwards through differen levels of intercourse

He and I got properly messy for like six hours straight. Leashed and collared, burnt me-with-a-joint, almost choked me out, and coated my face. It was some fantastic Fourth Base shit, bud.

BHA (Based on health advice)

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"
