This word has been used for a couple I hang out with. A friend said, " They are in the Love "Bubble".
Meaning they are so in love that they are oblivious to what is going on around them. They are in the "bubble". The " Love Bubble".
A relationship between two people that cannot be penetrated or interrupted. Two people who are in love and don't notice anything going on outside of their Bubble. To be in the bubble you are oblivious of your surroundings. A relationship that is so hot you only see each other. You are in the Bubble!
To simply invest money with the purpose to make a profit. Bubble is to make something more than what it is. When you blow bubbles they multiply. I'f you say I'm blowin bubbles, this means to re-invest profit to make more money. If you say I'm tryna bubble, it means to make a profitable investment.
