What does ギスる mean?


Conversation goes:

> A: まだひきずっていたのか
>
> B: え、お前忘れたの？ **ギス** ってたの俺だけ？びっくりする
>
> B: 次はねぇぞ

The ギス I know means having a cold atmosphere or strained relationship. But
here, I am not sure I get what it means.




I'm Japanese.

As you said, **ギスギス** means having a cold atmosphere or strained relationship
even if it is a stranger, a slight friend, or a best friend.

In the same way, " **ギスってる** " means a relationship gets strained.

The difference between " **ギスギス** " and " **ギスってる** " is " **ギスギス** " just
represents the state of strained atmosphere or relationship while "ギスってる"
means a relationship gets a strained atmosphere or relationship.

Though there's not enough context to explain the conversation I'll try to: "
**ギスってたの俺だけ？** " means B had thought "A must be having grudge against me even
now" until A said I don't mind it now. B realized it was actually different.

Translated:

> A: Then, Are you feeling sorry about it even now?
>
> B: So don't you mind it , do you?

Alternatively, there might be another explanation: B had been hurt by A. It
was a long time ago, so A didn't think B was holding a grudge against them in
the present. And so A said "まだひきずっていたのか".

It is often used in informal relationships, especially in online gaming.

Used like this:  
"ギスギスした"  
"ギスるのが怖い"  
"ギスった"

As often happens in Japanese, nouns are often used as verbs when used with "
**する** ", "ってる","してる" and so on.

(Thanks a lot for correcting my English)
