What does gaf mean in Irish slang?

In Irish slang, gaf or more commonly spelled gaff is a very widely used term that means house, home, flat, or place of residence, and by extension a party or gathering at someone's house. For example, an Irish person might say we'll have a few cans back at my gaf meaning let's go back to my house to have some drinks, or is the gaf free meaning is your house empty of parents or roommates so we can hang out, or massive gaf party meaning a big house party. The term comes from old Irish English and Dublin slang, with roots in Romani and British thieves cant where gaff meant a cheap theatre or dwelling, and it became deeply embedded in Irish working-class slang in Dublin, Cork, and Galway. In modern Irish English, gaff is used daily by young and old, neutral and not offensive. It also appears in phrases like gaf on the piss meaning going out drinking from house to house, or gaf lad meaning someone who always hosts. The spelling gaf is common in texts and social media as shorthand for gaff because the double f is often dropped in quick typing. It is one of the most characteristic Irish slang words alongside craic, grand, and sound, and is understood throughout Ireland, Northern Ireland, and among Irish diaspora in UK, Australia, and US. It should not be confused with gaffe meaning mistake.
