Titty Sucking Lips

Like DSL's, but on straight men. Celebrities with big, full titty sucking lips include Channing Tatum and Mick Jagger.

Girl: check out that guy sitting there, he's hot and has nice lips.
Friend: Hahah those are some DSLs

Girl: Nah they're TSLs. I want them nibbling on my nipples right here, right now, on the dance floor.

TSL 

Stands for Totally Stifling Laughter. For all those times you get a funny text, read a hilarious e-mail, or receive a joke over IM while at work (or another place deemed inappropriate to laugh out loud).

"Oh man, I'm TSL because my boss just walked by!"
