full-on

Holding nothing back

Full-on means complete, intense, or without restraint.

A full-on assault holds nothing back.

A full-on commitment is total.

The phrase often emphasizes that something is the real or extreme version rather than partial or diluted: It wasn't just flirting—it was a full-on affair.

Chiefly British, though increasingly common in American English.
