Bubsies,
while still in the growth process,
pre-teenage girls develop pre-boobs, referred to formally as twits.
Twits simply look like constantly pointy nipples.

TWITs stands for 'Teenage Women in Their Thirties' and refers to 30-something women who have extended their adolescence, as well as those who, after starting a family, have entered a second teenage lifestage. The poster girls might be Pink, Victoria Beckham and Gwen Stefani.
As noted by Australian social researcher Mark McCrindle (www.mccrindle.com.au), the popularisation of lifestyle segments began in the 1980’s most notably with the Yuppies (Young Urban Professionals) and then the DINKs (Double Income, No Kids). The 1990’s introduced us to the SNAGs (Sensitive New Age Guy) and the WAGs (Wives And Girlfriends –notably of sporting stars). Other recent labels include KIPPERS (Kids In Parents' Pockets Eroding Retirement Savings), NETTELs (Not Enough Time To Enjoy Life), the Downagers, the Silver Stylers and the Boomerang kids.

The plural future tense of the word "tweets." Often confused with the word "twit" which is someone who is socially inept. This word came into widespread use with the rise of the social networking and microblogging website Twitter.
