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:

fast
[...]
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)

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.
