Thrashing around in stinging nettle with someone else's dick 

Used as an expression for people who enjoy benefits while someone else is taking the risk for it, and therefore they can give false advice, act irresponsibly without retribution.
Often associated with golden boys, politicans, or people in high positions.
Originated in Hungary.

It's easy for the politicans to pass a new act, they are thrashing around in stinging nettle with someone else's dicks, not theirs.

Indie Thrashing

Indie Thrashing (verb)

Definition: To render someone speechless from mentioning an indie band they’ve never heard of, the more obscure the better.

Person A: Fotos 3rd album is a let down.
Person B: Why?
Person A: It’s not as good as their second album Nach Dem Goldrausch, it's too post-rock influenced instead of their signature indie pop, they need to go back to their roots.
Person B: Well I don’t know what to say to that.
Person C: Dude, you just got a real indie thrashing.

Thrashing 

Like head banging only better and more fun..
You get your arms T-rexin' and move them rapidly and head bang while whipping your hair around .
may appear like your having an epileptic seizure

Head banging with more hair flipping, arm moving and gracefulness ... "Thrashing it out"
