look up any word, like the eiffel tower:
Banapple (gas) is an illegal substance that contains traces of LSD given a fruity flavour.

It was first discovered in 1968 and popularised by the famous singer, Cat Stevens (now known as Yusuf Islam), in his song 'Banapple Gas'

It is classified as a class-A drug

Similiar to shinanigans, Banapple is declared when someone or something is just plain rediculous.
Banapple can also be used as a adjective or adverb describing a thing or person in seriously douchy way.
Boss: "You have to wash all those dishes before leaving."
Employee: "Banapple!"


Boss: "You have to was all those dishes before leaving."
Employee: "This job is fucking banapple..."

Jim saw a banapple in the kitchen and his mother look at him and said "don't be a pervert"
