Didicoy (Romani: didikai; also diddicoy, diddykai) is a term of the Romani or "Gypsies" for "Gypsies" and travellers with mixed Romani and non Romani blood.
An example of an old Romani song about a mixed blooded Romani is the "Romano Rai" (or "Romany Rye"):
I'm a Romano Rai, just an old didikai,
I build all my temples beneath the blue sky,
I live in a tent and I don't pay no rent,
and that's why they call me the Romano Rai.
Didi-a-didi-a-didi-di-kai, chavves,
Tika-dika-tika-a-lai, (or can be; Kakka Chavve, Dekh akai)
Your Daddus tryin' to sell a mush a kushto grai.
I'm a Romano rai, just an old didikai,
I live in a mansion beneath the blue sky,
I was born in a ditch, so I won't ever grow rich,
But that's why they call me the Romano Rai.
Tikka, tikka, didikai, tikka, tikka, didikai
That's why they call him the Romano Rai
Tikka-tikka-didikai, tikka tikka, didikai,
That's why they call him the Romani Rai.
I'm a Romano Rai, a true didikai,
My temple's a mansion beneath the blue sky,
I'm a Romano Rai, a true didikai,
just campin' around, on any ol' ground,
