because "piss on your chips" means

[username34939508]

something different to me than the way it is used here?

My definition:

To put yourself at a long-term disadvantage through a foolhardy short-term action.

Whereas on MN it seems to mean spoiling someone else's fun.

I'm with you OP

I use it when someone's in a bad tempered mood. 'fuck me, who pissed on your chips like?' because someone pissing on your dinner would be a sure fire way of putting you in a bad mood.

spoiling someone else's fun is pissing on THEIR chips, I would think

Yes, it's 'who pissed on your chips' as in who spoilt your fun. It's not the same as shooting yourself in the foot

Here it means if someone pisses on your chips, or on your cornflakes, they are spoiling your fun.

Pissing on their 'flames' where I came from, but yes, spoiling their fun.

Here 'who's pissed on your chips?' means 'who has upset you'

Or

'Well, that's pissed on your chips' means 'that has gone wrong for you hasn't it'.

Or

'You've proper pissed on your chips now' means 'you have made an error that will have consequences'

Spoiling someone else's fun like "rain on your parade"

Yeah

Who pissed on your chips, don't you piss on my chips would be regarding fun

Cut off nose to spite your face would be regarding long term disadvantage

I use it in the same way as yould say "rain on your parade". Ie. Being a spoilsport/ dampening the mood of something which would otherwise be fun.

Pissing on someone else’s chips is spoiling their fun/day/activity/whatever.
Similar to when someone is in a bad mood and you ask ‘who pissed ok your cornflakes this morning?’
So you believe it means similar to ‘cutting your nose off to spite your face’?

Pissing on your own chips means ruining something for yourself.

I will your OH ‘I don’t mean to piss on your chips but it is not a good idea to let the cat cuddle the hamster’

Username I think that's more "Pissing into the wind".

Same as Ditto - similar to raining on a parade, ie dampening an experience and spoiling it for self and/or others.

I've always understood it as meaning you had some simple but valued pleasure (chips) which someone had ruined out of sheer spite (pissing on them).

Just because they could.

It means ruining something for someone. What you are thinking sounds more like cutting off your nose to spite your face.

To put yourself at a long-term disadvantage through a foolhardy short-term action.

How have you put yourself at a long term disadvantage if someone else has pissed o your chips, though? This doesn’t make sense to me.

I thought the chips were the gambling kind, not the dinner sort.

Yeah it's the same as when someone shits in your mince 😂

Loving the definitions, it's the fun sponge one for me though

I like :
'Pissed on your bonfire"
to ruin someones fun.

I've always understood it as meaning you had some simple but valued pleasure (chips) which someone had ruined out of sheer spite (pissing on them)

This exactly

I've only ever heard it used like "who rattled your cage" if someone seems to be in a bad mood

It's like 'raining on my parade' I use it to mean ruining someone's fun or spoiling something out of spite.
