It's called Fancy Stitch to the combination of two or more than two basic crochet stitches.
In this way, you can create according to our imagination, very many other points that will be renamed Fancy Stitch. Fantasy stitch can also have a specific name given by its creator.
This is an example of Fantasy point where two basic points are used:
Crochet a chain base.
Work first row in Double Crochet.
Work the second row as well: * 1 d.c stung on 1 d.c of the previous row, 1 ch., jump 2 st., on the 3° d.c 4 d.c, 1 ch, * jump 2 st, rep. from * to * throughout the row.
Work the third row as well: * 1 d.c stung on 1 d.c of the previous row, 2 ch, 1 incomplete d.c at each d.c (the arc of 4 st.) of the previous row and then, closed them together, 2 ch. * Rep. from * to * the entire row.
Then keep repeating those three rows.
