there are two kinds of all-body sex:
1) the dick is in the vagina, the chest is pressed against the boobs, making out, and the man's fingers are fingering the woman's ass, and the woman the man's.
2) someone lying on his/her back, and every body part is being done sex with.
"I just did all-body sex!"
"nice, which kind?"
"both!!!!!!!!!!"
The attempt to maintain and/or improve your weight and appearance by going to the gym, while you're significant other has left for a significant amount of time, since you now find yourself with free time (time usually spent with him/her). In order to maintain a closeness while there is an absence of physical interaction, you begin sending "sexting" photos to remind him/her how sexy and badass you still are while showing off your newly found hours at the gym and to prevent any possible thoughts of straying.
i.e. "awe my boyfriend just left for europe for a month. I can't eat that, I have to not gain anything before he comes back. I'm hitting the gym. Gotta get my sexting body on!"
A "human" that spends so much time playing video games that their posture is level nerd neck. Everytime anyone goes tryhard they hunch down and their neck gets longer there fore a nerd neck is always hunched down cause they're always going try hard. In other words a nerd neck is a try hard, since their neck is 100% longer than the average human being due to playing too many video games and taking them serious, nerd necks are not even considered human anymore but something more sad. Nerd necks are often found on fortnite, their natural habitat usually being tilted towers.
