The correct spelling of the phrase "getting smoking" is actually "getting smokin'". The apostrophe represents the missing "g" sound at the end of the word "smokin'". In IPA phonetic transcription, the word would be transcribed as /ˈɡɛtɪŋ ˈsmoʊkɪn/ with the stress on the first syllable of "getting", the long "o" sound in "smoking", and the glottal stop in place of the missing "g". This phrase is often used informally to describe something that is exciting or exceptional.
There is no specific term "getting smoking" in the English language. It seems to be a phrase or expression that may have been used in a particular context or by a certain group of people, but it is not widely recognized or included in dictionaries. Therefore, it does not have an established dictionary definition. It is important to note that there are other related terms such as "smoking" which refers to the act of inhaling and exhaling the smoke of burned substances (usually tobacco) through a pipe, cigarette, or other device. Additionally, "getting" can refer to obtaining or acquiring something. However, without further context or information, it is difficult to provide a specific definition for "getting smoking".
