when a girl wants a lot for christmas, more than she actually deserves and realises the only way to get this is to promises sexual favours to her boyfriend ie 4 of the magic 5 (handjob, blowjob, fingering,licking out, no sex). she promises this but has no intention of actually doing any of it because she is EVIL.
tom: i cant wait till tonight its gonna be amazing.
4 of the magic 5! yessss!
dario: you do realise shes joking right?
tom: what no way she'll definetly do it she loves me
dario(whispers): christmas tease
dario: i said christmas tease you dumb bastard hahahahaha
*tom* cries until he passes out
