Used primarily in the context of fashion and clothing, means to steal or directly copy another person's style - often in an act of jealousy or unoriginality.

The implication of doing a Gomez is that you'll end up looking like your mate by copying him or her - see also, sheep.
"Yeeeah, she did a Gomez and bought those jeans that Katie has"

"Mate, Jon just Gomez-ed your scarf....twat"
