A mildly vulgar slang phrase meaning absolutely nothing — a more emphatic version of 'nothing at all,' used to express frustration or dismissiveness. Functionally parallel to 'bugger all' or 'sod all' in British registers. Typically deployed when someone has received nothing, achieved nothing, or been left with nothing after an effort.

I waited for two hours and got jack all for it.
Origin: Derived from 'jack shit,' with 'all' reinforcing total negation. Part of a family of informal 'nothing' expressions in English. Editorial expansion authored on Slangora.

(mildly, vulgar, slang) Nothing.

For parents

Jack all means: Nothing.. It is informal slang, fine in casual speech but not suited to formal contexts. It carries sexual or vulgar connotations; not alarming on its own but worth understanding the context your teen heard it in. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.

For ESL learners

jack all means: Nothing.. Register: very informal, often derogatory or vulgar. Avoid in formal, business, academic, or polite writing. Even in casual speech the word can offend and is best left out of a learner's active vocabulary. A common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; native speakers immediately notice when slang appears in formal contexts, so always check the surrounding register before producing it yourself.
