No it doesn’t have to mean anything besides: “BWAHAHAHAHAHA!” (Pic from Alfred Sim). Scroll down for an explanation of WHAT a “Longan” is, followed by the 'His Time Has Come' TV Spot … because it’s not all about “fruits” :)
"Dimocarpus longan, commonly known as the longan (UK: /ˈlɒŋɡən/; US: /ˈlɑːŋɡən/, /ˈlɔːŋɡən/), is a tropical tree that produces edible fruit. It is one of the better-known tropical members of the soapberry family (Sapindaceae), to which the lychee also belongs. Included in the soapberry family are the lychee, rambutan, guarani, koran, pitomba, Spanish lime and ackee. Longan is commonly associated with lychee, which is similar in structure but more aromatic in taste. It is native to Southern Asia." (Wiki)
"Logan is an upcoming American superhero film featuring the Marvel Comics character Wolverine distributed by 20th Century Fox. It is intended to be the tenth installment in the X-Men film series, as well as the third and final Wolverine solo film following X-Men Origins: Wolverine (2009) and The Wolverine (2013). The film takes inspiration from Old Man Logan by Mark Millar and Steve McNiven, which follows a past-his-prime Logan undertaking a final adventure in the post-apocalyptic future.” (Wiki)
