To be laviscious is to exhibit certain unattractive character traits including cruelty, manipulation, double standards and being a big fat meanie. It does not take much to trigger this characteristic in these nasty individuals, just being happy and having fun should do it. A laviscious person will move outside the law and stalk you (especially if you are attractive to them), hax your tech (hax ikr) and listen to your private conversations but usually will only do this to the vulnerable such as women, children and gay moms. These narcissistic folk tend to have equally morally bankrupt 'friends' and will stop at nothing to hurt people who exhibit 'weakness' such as being kind, helpful or angelic. Lavisciousness includes a perchance for poorly written creative writing and the making up of very nonsensical stories about themselves and their lonely, boring lives. You would be forgiven for sitting on the fence, being Switzerland or hedging your bets when the lies and corruption begin out of intuition or self defense. One must never give money to a lavisciouss person, remaining pennywise is advised at all times as is wearing your sexiest camo print and push up bra to avoid detection. Always sing to a lavisciouss person, especially when they are stalking you at Funday Friday, they love it.
