In the Underworld series lycans are a werewolf species, so he’s claiming to be half wolf and half werewolf, which is half wolf half human. If my arithmetic is correct, that would render him three quarters wolf and one quarter human.

They each have their own skeletons in their closets and he considers himself lucky that she doesn’t define him by his past.

This line is a reference to “The Bridge Wars”, a heated feud between Bronx rapper KRS-One and Queensbridge group Marley Juice Crew over the true birthplace of the genre.

Saigon did a song DJ Cocoa Chanelle produced with Trey Songz on the hook entitled “Pain in my Life”.

He’s saying that Saigon’s response was a essentially a joke and that he should get any of the well regarded battle rappers listed to assist him in his dissing and help him freshen up his battle rapping style and rhymes.

He’s experiencing a manic high. As with many people who’re bipolar, which accounts for only 2.6% of US adults, it’s a mental state incredibly difficult to describe to others who haven’t experienced it themselves. The high level of mental stimulation that causes a mania is characterized by a flight of thoughts and delusions of grandeur resulting in a sense of being clairvoyant, or “having a 6th sense”.

A symptom of Bipolar I disorder is periods of mania, which can include psychosis. It’s defined as losing touch with reality and the physical world around you.

In this context it’s a result of the “manic high”, or mania, where the brain is extremely overstimulated often eliciting a sense of euphoria. When this goes on for too long it can result in auditory/visual hallucinations, confusion, and paranoia. By some, a manic high has been compared as being similar to the use of stimulants such as amphetamines.
