In an informal conversation, cheorvah is used to substitute
something for lack of better term; used to immediately replace a word that takes considerably a long time to
remember in an informal conversation.
However, using cheorvah as a substitute for words in a conversation is not always advisable due to ambiguity.
One must elaborate if need be.
