What is Skillimanjaro?
1.
An abstract metaphor for getting to an amazing place after having 'taking the top off a few'. When one has climbed Mount Skillimanjaro, it is to mean that you are on top-of-the-world - thus, absolutley untouchable.
'Here Mate, I`m off mi trolley, Mead'.
'Yeah, me too - I`ve climbed Mount Skillimanjaro'.
Madness usually ensues.
