too scared to Google

I was on tribe.net earlier, and decided to see who else had listed Saline - my hometown - in their profile. I was shocked when hundreds of entries popped up. And then confused, when I realized that most all were leather types. And then I completely lost the plot when 'Saline' was listed in their interests column. As in Profile Name: bootmaster. Interests: piercing, sounding, fisting, catheters, electro, pumping, and saline.

I don't know what the hell it is, and I'm not about to google it on a work computer. Judging from the context, I'm pretty sure it's hard-core and disturbing. I'll call Madame Lim and see what she says.
