Is there a specific word for the condition of deliberately reacting against someone else's behaviour because you they get on your nerves?

[Tinker]

I'm thinking there should be good German word to describe, for example, becoming very moody and monosyllabic when you're with someone who won't shut up.

Deliberately taking a stance on something which isn't what you actually believe but just because it's the opposite of whoever you're talking to

God, this all sounds a bit heavy now - it's meant to be more light-hearted than it sounds.

I don't know the word but I have got the condition

arsey?

inlawitis

Contrary.

Ta dah!

As in "Mary mary quite contrary" rather than "contrary to popular opinion".

My DD is nearly 2 and it describes her perfectly

contra-suggestive?

pmt?

I call it "dealing with my grandmother".
So "Grossmutterstummgemachen"?

Hmm, contrary is close but not quite what I want. Definitely needs to be German, along the lines of schadenfreude

I was gonna say contrary too

There is another word too though.......tip of tongue.....no can't think of it

Contrary in German:

noun:

Gegenteil

adjective:

entgegengesetzt
gegensätzlich
gegenteilig
gegenläufig
umgekehrt
trotzig
widerb orstig
widersetzlich

Some sound like possibilities.

Well bleedin eck tinker! What do you want, blood? Close but no banana eh?

Bloody minded?

No hassled, that's not german enough...

Could describe tinker though...

devils advocate?

No, not bloody minded or devil's advocate. More a mixture of truculent and moodiness. Maybe it's just Adolescence.

awkward?

It is contrary, as others have said.

trolling?

Gegenteil seems to be it though...

I have the condition too! We need someone like frogs or emkana to help us find the right German word. I do like trotzig...

Nah, trotzig sounds like a vicious D'n'V bug

oppositional defiance,
sounds about right.

just ODD
