To repeat something with reckless abandon using 「まくる」

<div class='writeup-body'>まくる is a verb that will be attached to the conjunctive form of other verbs in order to show that (A) is being done over and over, a lot, or with a great amount of vigor. It comes from the verb う-Verb 捲（まく）る 'to roll', or 'to turn', so means 'to do (A) around and again'. Common translations include 'to (A) like crazy', 'to do nothing but (A)', and 'to constantly do (A)'. 
As mentioned, this structure will attach to the conjunctive form of other verbs.<ul class='writeup-examples--holder'>

This structure may be used both in positive or negative contexts, and it is quite common for the nuance of まくる to indicate that (A) is being done recklessly, or with abandon. This implies that the speaker isn't thinking about the consequences of doing (A) repeatedly, if any may exist.
<div class='writeup-caution'><div class='caution-header'>Caution</div>The (A) verb must be something that is volitional, meaning that the speaker must have control over it and its repetition.<ul class='writeup-examples--holder'>
