I could be wrong, but I think the delay term comes from BMS charts. If you're familiar with EOS, you should instantly recognize how the keysounds create a delay effect by being triggered so quickly, with the same sample being keysounded on multiple notes in a stream.

another example of delay patterning is the synths used in this Tiro Finale chart

I think this is the clearest example of a delay chart though, Central Delay

You can audibly hear how the sound of the keysounds sounds weird when it gets super dense, because the keysound samples are being (I think) cut off and retriggered by a later note, creating what amounts to a sort of delay effect (think echo effect. in music mixing, echo effects are referred to as delay effects).
In terms of patterning, you can see there's some diversity in the sort of streams used in each chart. Some prefer bursts of stairs, some use chordstreams, etc.

iirc it's mapping long sounds as a stream, altho im able to recognize it when I see it I honestly wouldn't be able to tell exactly what it is so dont quote me on that e
That would be one technique for creating dumpstreams, rather than delays.
