Dialectal Variation
British vs American Usage
Differences
The technical meaning is identical. The vulgar slang meaning is almost exclusively British. American English lacks this slang connotation.
Connotations
In UK, the word carries a potential double entendre risk in non-technical contexts. In US, it is purely technical.
Frequency
Higher frequency in UK due to dual usage (technical + slang). In US, frequency is confined to technical/industrial domains.
