Best Answer

Riffing means improvising.

Riffing, or to riff, comes from music, specifically:

riff (verb) 1: an ostinato phrase (as in jazz) typically supporting a solo improvisation

also : a piece based on such a phrase

2: a rapid energetic often improvised verbal outpouring

especially : one that is part of a comic performance

Merriam-Webster Dictionary

In the example, the second speaker is contrasting the first (saying the opposite):

“That wasn’t a brilliant strategic play, that was improvising.”

Another example outside of music would be the phrase:

Robin Williams riffed with Steve Martin on stage.

See examples of this usage on Open Culture, the New Yorker, The Christian Science Monitor, and many others.

Robin Williams was a famous American comedian who was famous for his improvising, and there are tons of articles online about him riffing with other comedians or at live events.
