Beat the boss once and it's over. Beat him repeatedly, it's more satisfying.
People assume that when you try and understand Lacanian theory, your life only becomes more complicated. When it, in fact, gets so much simpler. What's the first word that comes to mind when we think about Lacan? Desire, that's right. This type of desire; however, is arguably a thousand times more powerful than the straightforward desire for a peanut butter sandwich. Unless you really are only asking for this sandwich because you know your crush loves having it, then that's a different story. But, even then, mustn't there be a reason behind them loving it? Enough about nut butters.
See Lacan Coven section for an in-depth explanation on desire alongside other topics.
