DFK stands for deep French kissing. It is advertising shorthand rather than a defined service — what it covers is whatever the person advertising it says it covers, and it is agreed directly in advance.
Initialism of deep French kissing.
This is advertising shorthand, and the distinction matters more than it looks. An expansion is not a specification: knowing what the letters stand for tells you the emphasis being advertised, not what any individual offers, on what terms, or whether they offer it at all. Two listings using the same letters may mean quite different bookings.
The abbreviation is attested in how people actually write rather than in any official list. A corpus study of a large UK sex-work forum found dfk among the abbreviations clients use most, beside the shorthand for bareback, reverse oral and oral without. Its authors read the habit as a practical need to discuss these subjects routinely, and note it may also make otherwise taboo discussion easier.
Whether kissing is offered at all is the individual's decision, and it is settled in the conversation rather than by the letters in a listing.
Terms are agreed directly and in advance in every case; we do not publish rates as fact anywhere on this site. Country rules differ — see our legal status hub.
Frequently asked questions
What does DFK include?
Whatever the person advertising it says it includes. There is no agreed definition to appeal to, which is precisely why it is worth asking rather than assuming.
Is DFK a standard service?
No. It is advertising shorthand. The letters tell you what is being emphasised, not what is on offer, and two listings using them may mean quite different things.
How is DFK different from GFE?
GFE describes a whole booking styled as companionship. DFK names one element that may or may not form part of such a booking. Neither is a defined service, and one does not imply the other.
