Douche Grenade

When a person no one likes enters a conversation, therefore making it awkward, a douche grenade has been dropped. Named because the person's comments affect everyone in the group, like shrapnel from a grenade.

A female douche who is usually overweight, slightly attractive when you're drunk, but completely loses their attractiveness once you're sober again. They are purely annoying and you can't stand being next to them for one minute. Almost like a douchebabe minus the hotness.
