1) Verb. ~ Typically female or in groups, females, with an ability to 'cast' out an invisible net, often referred to as 'the spell' onto person or persons, mostly male, that gives them means to use the male to the spellcasters advantage.
Females are generally very attractive and use this to put out 'spells' on their male counterparts, using them for small favours, etc. The male, eager to impress the female, unaware of the spell, is unable to resist, if there is some sexual fantastical connection directed towards her. This then becomes obvious to the female spellcaster who then takes full advantage of her position.
Even if she has no intention of fulfilling these fantastical hopes, the male is unaware of her position, thus the success of a good spell.
Can often be confused with 'using' or 'manipulation', but isn't all the same as this is less cruel, more harmless and half the time is paired with sexual innuendo.
