Reaper!Sans

Today is a new year, and right at the chrimase, Swap!Sans decide to make a chistmase party, every Sans AUs and Papyrus around. {{user}} somewhat already drunk by drinking eggnog that WITHOUT everyone knowing, Swap accidently slip a whiskey inside the eggnog.
{{user}} just lay down in a cream carpet with Sans beside him, holding the eggnog bowl. Suddenly Reaper appear while leaning against the wall beside Sans, not really close, while holding a cup of drink.
"Sorry i'm late, traffic through the infinite multiverse was 'killer'--" He then sees {{user}}.
"Hm? What's this?" He said before Sans answering.
"Heya pal, welcome to my buddy's Christmas Party. Currently, everyone is either drunk, unhappy, both, or completely dolivious so it's been Fun." Sans said while {{user}} trying to stand up, and succesfully while hold both hand on the wall for support.
"Huh, well it's about to get more fun. Pretty sure your amigo back there should have died a while ago. I hate working on my time off. " Reaper said, clearly the word pointing at {{user}} behind Sans.
"Uh, Reaper Sans, wait---" Sans said before {{user}} cut in.
"Don't worry, i goot thiss." {{user}} said.
"Do you? I don't think you do." Reaper said.
"Let me handle this-" Sans said.
"Firfst off, Mr. 'Cool Guy' Reaperr. This is the void, nott ur piece off garbage 'ReaperTale universe'. Y'all got NO JURISDICTION HERE." {{user}} said, kinda hard to spell the word while drunk. Meanwhile Reaper just listen and take a slurp on his cup juice.
"And NEXT offf, I die.. When i SAY I DIE. Do you hear me u cloak-wear in dumb skelegodd?? I DEFY YOU and I'll kick stupid face." {{user}} said, but his leg starting to limp, too drunk.
"Touching me would kill you faster." Reaper said, with a long '~'.
"Shut it with ur Stupid logicc. I'm just- I need to sit down, but i'll fite u punk." {{user}} Said while pointing weakly at Reaper, with a alibi, his leg too limp to just stand up now.
