Blag

Comes from the old word "blackguard", a contemptible and untrustworthy person, which was pronounced "blaggard".

The sound of the last part "ard" became confused with the suffix "ard": meaning a person who does an action, as in drunkard. "Blag" becoming the contemptible untrustworthy action.

I first came across it as a teenager working on a building site nearly 50years ago, when an old Irishman accused another of "fucking blaggarding". I didn't know what it meant, but was obviously a bad thing to accuse someone of and not done lightly. These days it seems to have lost its former vehemence and is used more in the manner of petty criminals boasting of their offences.
"Where did you get that from?"
"Ha ha ha, fucking blagged it didn't I.

"Did your wife say anything about the time you got home?"
"Yes, I gave her some blag about working late."

Cockwomble

Now a general word of abuse, but originally more especially for politicians. However, I'm fairly sure its first meaning was something rather more specific.
"The Wombles" was a children's TV programme about little creatures who lived in Wimbledon Common and picked up trash.

Also at one time Wimble Common was known as a place homosexual men would go in the evening in search of anonymous casual sex.

There was a scandal once regarding a politician who was seen there one evening and who insisted he was, "Taking his dog for a walk".

So a "cockwomble" was someone (especially a politician) whose interests include anonymous casual homosexual sex acts with strangers.
"Why does he go by car to take his dog for a walk?"

"He's a cockwomble."

Frontyard hard

Refers to a time when you trained martial arts, but didn't have access to martial arts classes and did all your training in the front yard.
Also it's about making stuff happen when you have very little.

The expression was coined by a member of the group Da'Mon Stith trains with. First recorded use was by Da'Mon Stith in a Facebook livestream on 7th July 2020.
"Tell us about when you first started martial arts."
"It was all frontyard hard where I was a kid."

tallywagon

Name given to the Toyota Hilux pickup truck, originally by British soldiers, because of it's popularity with the Taliban in Afghanistan.

First came across the word in a novel by Andy McNab (forget which, but think it may have been"Exit Wounds").
"Where's your truck parked?"
"It's the the tallywagon over there."

Rawr

I thought it came from the old joke,

You: What winks and fucks like a tiger?"

Them: "I don't know."
You: wink and make a tiger noise.
"What winks and fucks like a tiger?"

"I don't know."
"Rawr."

Salty

I thought "salty" only very recently acquired this meaning (see the other entries). However, I came across it in a book published in 1969 "The Moon is a Harsh Mistress" by Robert A. Heinlein near the top of page 32.
'Don't jump salty, beautiful"
