No cap is similar to “no joke” or “absolutely”. Thirsty in slang means someone who is always looking for attention or affection. BC 459 means “because I love you”. I have a 13 year old :-)
There are vegans/vegetarians who (used to) enjoy the taste of meat, but have chosen not to eat it due to the extreme cruelty and abuse in the animal agriculture industry. It’s a way to eat something similar to meat without having to participate in the horror. Also, plant-based food has come a long way. A lot of it is now quite delicious in it’s own right!
Not really. It just means you are a lot, over the top, or dramatic.
