Bodyshakin'

The speaker describes being unexpectedly overwhelmed by attraction. At first, he presents himself as independent and confident, someone who avoids falling in love. Meeting this person changes that: he feels nervous and physically excited, and he begins to imagine a lasting relationship rather than a brief encounter. The repeated chorus keeps the focus on this powerful, almost uncontrollable reaction.

Several images make the change vivid. “Emotional armour” suggests the defenses he built to avoid being hurt; the other person has “pierced” it, so he can no longer keep his feelings at a distance. The “bolt of lightning” and “hurricane velocity” compare attraction to sudden, intense forces of nature. “Shaking to the bone” is an idiom meaning to tremble deeply, though here it may also convey excitement rather than fear.

The song mixes playful confidence with genuine vulnerability. The speaker says he has a “secret weapon” and wants the other person alone, which can sound flirtatious and self-assured, while his claims that he wants to be a lover, friend, and lasting partner suggest more serious hopes. It is unclear whether this is a settled commitment or an enthusiastic promise made in the heat of attraction.
