Guaranteed Term Life Insurance is probably referring to Term Life Insurance where the premium is guaranteed not to go up in price for the entire term. E.g. If it is Guaranteed 20 year Term, the price will stay the same for 20 years.
The other option is that the term policy does not have any health questions, and one is guaranteed to get it. But I am not aware of any term policies like that. Most guaranteed issue life insurance is Whole Life.
