Dialectal Variation
British vs American Usage
Differences
'Bang' as a hair fringe is primarily North American. In British English, the same hairstyle is usually 'fringe'. The intensifier usage (e.g., 'bang on') is more common in UK English.
Connotations
The slang meaning 'to have sex' is considered vulgar in both varieties. As an intensifier, it feels more informal and emphatic in the UK. The noun for a sudden thrill (e.g., 'get a bang out of') is slightly more American.
Frequency
Overall frequency is similar. The literal noise/impact sense is core in both. The hairstyle sense is highly marked as North American.

- Overusing the slang meaning in formal contexts.
- Confusing 'bang' (noise) with 'bank' (financial institution) in spelling/pronunciation.
