A rawrasaurus is one of your closest friends, someone you love to no end, and a person you would give everything for. Most often, you could never live without this person, and if you did, you'd be lucky as hell. You couldn't even think of parting from them for too long. This person feels the same way. A rawrasaurus is also a word for someone you love like this but are not in a realtionship with them for any said reason.
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
