Meaning & Usage
"badmouth / trash-talk"
To criticize or badmouth someone, usually behind their back. Different from 'slag' (the noun insult) — 'slagging off' is the act of speaking negatively about someone. 'Slagging' in Irish English can actually mean playful teasing between friends, which is a completely different vibe.
Examples in the Wild
'He's always slagging off the boss behind her back.' Irish: 'The lads were slagging me about my haircut.'
Regional Variations
'Slagging' means friendly teasing, not hostile
Means badmouthing, more negative
When to Use It
Context
- Casual conversations with friends

Cultural Context
British and Irish English. 'Stop slagging me off' means 'stop talking shit about me.' In Ireland, 'slagging' your mates is a bonding activity — the more creative the insults, the closer the friendship. This Irish usage has no edge to it; the British usage does.
