valid

‘an expression of agreement, a synonym of OK, a good excuse’

Valid is a slang phrase meaning “good excuse” or “OK.” This word comes from English and literally refers to something meaningful, legitimate, lawful. In Polish Internet slang  it has become accepted as an expression of agreement with someone’s explanation.
At the beginning, “valid” was used in Internet conversation (e.g.in chat rooms, on social media), to emphasise that someone’s argument or reason is logical and acceptable.   With the passing of time, it has gained popularity among younger speakers, who use it every day conversations, not only online, but also in their daily lives.  It is also used in an ironic manner, when speaker hesitate about validity of someone’s explanation, but wants to interrupt discussion whit a phrase like “alright”.
