Does anyone have an idea? Close friends? I usually see this term in stories where the friends were best friends and then they fight for some reason.

From Merriam-Webster:

2 : firmly loyal <became fast friends>

From Wiktionary:

Of people: steadfast, with unwavering feeling. (Now only in set phrases like "fast friend".) [from 10th c.]

Etymonline provides some background:

O.E. fæst "firmly fixed, steadfast, secure, enclosed," probably from P.Gmc. *fastuz (cf. O.Fris. fest, O.N. fastr, Du. vast, Ger. fest)

  • interetsing, i always thought "they became fast friends" meant "they quickly became friends" – Claudiu Oct 31 '10 at 0:13

    @Claudiu: that would be "they became friends fast" or "they fast became friends". Note how you didn't write "they became quickly friends". An adverb doesn't really fit in there. – RegDwigнt Oct 31 '10 at 0:24

    With the meaning of "firmly fixed", "fast" is also used in the phrase "stuck fast", to mean really, really stuck. – Steve Melnikoff Nov 1 '10 at 10:11

    @Steve: and let us not forget "fasten your seatbelts". – RegDwigнt Nov 1 '10 at 10:17

    I always thought that meant "make your seatbelts go faster!" – Rahul Nov 27 '10 at 1:06

The sense of "fast" here is almost obsolete; it's the "fast" of "steadfast," as noted by RegDwight above. It means "tight" or "secure," and you'll see it in literature in expressions like "hold fast" meaning to "get a tight grip" (on something). "Hold fast to your dreams" means to keep them close and never let them go.

Which is exactly what you should do with a good friend.


Fast friends are people who newly meet by circumstances but find themselves mutually trustworthy and so, bond together.

Fast friends means friends who spend most of their time in a day together. Or friends who are always seen together.

    That is not what fast means here. Your use of whom is also incorrect. – Janus Bahs Jacquet Mar 7 '15 at 9:43
