Там наверно перед этим что-то еще стояло. Например "to get into a pickle" означает "попасть в неприятную ситуацию". Скорее всего вся фраза звучит типа "I am a bit into a pickle" либо "I got myself a bit into a pickle", что значит "у меня небольшие неприятности".

Do you mean "they took a bite out of a pickle?" or "they got into a bit of a pickle" meaning that they got into trouble We ate Grandma's food for supper and every time she bit into a pickle she said,"mmm...nothing like the real thing!" This means that grandma was not happy with the inferior quality of the pickled cucumber. It was probably not home made.
