Correct spelling for the English word "Lizbiff" is [lˈɪzbɪf], [lˈɪzbɪf], [l_ˈɪ_z_b_ɪ_f] (IPA phonetic alphabet).
I apologize, but "Lizbiff" does not appear to have a commonly recognized definition in the English language. It is possible that the term is a neologism, slang, a name, or a term from a specific niche or community, which may not be widely known or documented in dictionaries. Without further context or information, it is challenging to provide an accurate definition. If "Lizbiff" refers to a specific entity, individual, or concept, it would be helpful to provide additional details to accurately define it.
