Random Riddle: Tasting Words

Liz, Mary, and Fred were talking to each other. Mary and Liz have been friends for many years, but they just met Fred a week ago and were trying to get to know him.

They started talking about computers, and after Fred had repeated the word, “Chip” a few times while talking about computer chips, Mary told him to stop saying it, as it tastes bad. Fred thought she was full of it, but Liz knew she was telling the truth.

How could Mary taste the word?
