signal boost

Spreading the word, or 'raising awareness' of an issue without actually doing anything useful (like, say, donating money). Popularly employed on Tumblr by image-conscious bloggers who want to look like they care deeply about a cause or issue, while they try to avoid investing any time, money or effort into said cause.

A Tumblr slacktivist reads a blog post from another Tumblr user who doesn't have enough money to pay rent and is shamelessly groveling for money on the internet.

Tumblr blogger: "Reblogging this is as good as giving money, right? I'll just tag it 'signal boost' so everyone knows how much I care about raising awareness and helping others."

significant other

Having a "special someone" in your life who causes you to submit gag-inducing, flowery descriptions of them to UD; usually descriptions include how amazing they are at their sport of choice, how large their genitalia are, and how incredibly hot they are. May also include line about how they are occasionally a jerk.

Jill: OMG! I'm going to send UD a def about my significant other Ryan, because he's just SO hawt and sexay, and he's so awesome at football, and he gives such good head! Except when he's a jerk, I mean.

signal to noise ratio

The ratio of what a woman says that makes sense to what she says that makes no sense.

This ratio is generally never greater than 0.5.

Man: I think my wife was trying to tell me something, but her signal to noise ratio was too low.
